concat firstname and lastname in child table

I was studying this string because I have a similar problem. I tried Eric's suggestion of redefining the recordset with the more complex query (with the concatenation) after the array definition server behavior. I found that this does permit the passing of the concatenated names, however, the array is no longer selected by the other variable. In other words, it lists all possible names, not those names that correspond to the selection of the parent field.

Here's the relevant php before the html page:
mysql_select_db($database_db, $db);
$query_contacts = sprintf("SELECT * FROM contacts ORDER BY contactID ASC");
$contacts = mysql_query($query_contacts, $db) or die(mysql_error());
$row_contacts = mysql_fetch_assoc($contacts);
$totalRows_contacts = mysql_num_rows($contacts);
?>
<?php
if ($row_contacts) {
echo "<SC" . "RIPT>\n";
echo "var WAJA = new Array();\n";

$oldmainid = 0;
$newmainid = $row_contacts["orgID"];
if ($oldmainid == $newmainid) {
$oldmainid = "";
}
$n = 0;
while ($row_contacts) {
if ($oldmainid != $newmainid) {
echo "WAJA[".$n."] = new Array();\n";
echo "WAJA[".$n."][0] = '".WA_DD_Replace($newmainid)."';\n";
$m = 1;
}

echo "WAJA[".$n."][".$m."] = new Array();\n";
echo "WAJA[".$n."][".$m."][0] = "."'".WA_DD_Replace($row_contacts["contactID"])."'".";\n";
echo "WAJA[".$n."][".$m."][1] = "."'".WA_DD_Replace($row_contacts["fullname"])."'".";\n";

$m++;
if ($oldmainid == 0) {
$oldmainid = $newmainid;
}
$oldmainid = $newmainid;
$row_contacts = mysql_fetch_assoc($contacts);
if ($row_contacts) {
$newmainid = $row_contacts["orgID"];
}
if ($oldmainid != $newmainid) {
$n++;
}
}

echo "var contacts_WAJA = WAJA;\n";
echo "WAJA = null;\n";
echo "</SC" . "RIPT>\n";
}
function WA_DD_Replace($startStr) {
$startStr = str_replace("'", "|WA|", $startStr);
$startStr = str_replace("\\", "\\\\", $startStr);
$startStr = preg_replace("/[\r\n]{1,}/", " ", $startStr);
return $startStr;
}
mysql_select_db($database_db, $db);
$query_contacts = "SELECT contactID, CONCAT(firstname, ' ',middlename,' ' ,lastname) AS fullname, orgID FROM contacts";
$contacts = mysql_query($query_contacts, $db) or die(mysql_error());
$row_contacts = mysql_fetch_assoc($contacts);
$totalRows_contacts = mysql_num_rows($contacts);
?>

here's the javascript code in the head of the html document:

function WA_ClientSideReplace(theval,findvar,repvar) {
var retval = "";
while (theval.indexOf(findvar) >= 0) {
retval += theval.substring(0,theval.indexOf(findvar));
retval += repvar;
theval = theval.substring(theval.indexOf(findvar) + String(findvar).length);
}
retval += theval;
if (retval == "" && theval.indexOf(findvar) < 0) {
retval = theval;
}
return retval;
}

function WA_UnloadList(thelist,leavevals,bottomnum) {
while (thelist.options.length > leavevals+bottomnum) {
if (thelist.options[leavevals]) {
thelist.options[leavevals] = null;
}
}
return leavevals;
}
function WA_FilterAndPopulateSubList(thearray,sourceselect,targetselect,leaveval,bottomleave,usesource,delimiter) {
if (bottomleave > 0) {
leaveArray = new Array(bottomleave);
if (targetselect.options.length >= bottomleave) {
for (var m=0; m<bottomleave; m++) {
leavetext = targetselect.options[(targetselect.options.length - bottomleave + m)].text;
leavevalue = targetselect.options[(targetselect.options.length - bottomleave + m)].value;
leaveArray[m] = new Array(leavevalue,leavetext);
}
}
else {
for (var m=0; m<bottomleave; m++) {
leavetext = "";
leavevalue = "";
leaveArray[m] = new Array(leavevalue,leavetext);
}
}
}
startid = WA_UnloadList(targetselect,leaveval,0);
mainids = new Array();
if (usesource) maintext = new Array();
for (var j=0; j<sourceselect.options.length; j++) {
if (sourceselect.options[j].selected) {
mainids[mainids.length] = sourceselect.options[j].value;
if (usesource) maintext[maintext.length] = sourceselect.options[j].text + delimiter;
}
}
for (var i=0; i<thearray.length; i++) {
goodid = false;
for (var h=0; h<mainids.length; h++) {
if (thearray[i][0] == mainids[h]) {
goodid = true;
break;
}
}
if (goodid) {
theBox = targetselect;
theLength = parseInt(theBox.options.length);
theServices = thearray[i].length + startid;
var l=1;
for (var k=startid; k<theServices; k++) {
if (l == thearray[i].length) break;
theBox.options[k] = new Option();
theBox.options[k].value = thearray[i][l][0];
if (usesource) theBox.options[k].text = maintext[h] + WA_ClientSideReplace(thearray[i][l][1],"|WA|","'");
else theBox.options[k].text = WA_ClientSideReplace(thearray[i][l][1],"|WA|","'");
l++;
}
startid = k;
}
}
if (bottomleave > 0) {
for (var n=0; n<leaveArray.length; n++) {
targetselect.options[startid+n] = new Option();
targetselect.options[startid+n].value = leaveArray[n][0];
targetselect.options[startid+n].text = leaveArray[n][1];
}
}
for (var l=0; l < targetselect.options.length; l++) {
targetselect.options[l].selected = false;
}
if (targetselect.options.length > 0) {
targetselect.options[0].selected = true;
}
}

and finally, here's the child list in the body of the document

<select name="contact" onchange="WA_FilterAndPopulateSubList(contacts_WAJA,MM_findObj('orgID'),MM_findObj('contact'),1,0,false,': ')">
<option value="" <?php if (!(strcmp("", $row_project['contact']))) {echo "selected=\"selected\"";} ?>>-- select --</option>
<?php
do {
?>
<option value="<?php echo $row_contacts['contactID']?>"<?php if (!(strcmp($row_contacts['contactID'], $row_project['contact']))) {echo "selected=\"selected\"";} ?>><?php echo $row_contacts['fullname'] ;?></option>
<?php
} while ($row_contacts = mysql_fetch_assoc($contacts));

?>
</select>


In case it's helpful, I'm also attaching the whole page. Oops, it won't let me attach a php file, scratch that.

Thanks for any help you can give me.
