Thanks Jason.
It does leave me with a couple of further questions which I will outline is a separate post
If anyone else is interested, here's what I did...
My recordset is based on 2 tables, tbllocation, with the name and address details, and tbllocationfacilities, which has a foreign key locationid and a description of each facility offered.
i then edited wagmp_map_1.php around line 260, so at the start of the do...loop, I build a string to create my facilities list...
<?php
// initialize variable to hold previous value
$previous = '';
?>
<?php do { ?>
<?php if (($row_rslocations['LocationID'] ."") == $previous ) {
$facilities .= '<li>'.$row_rslocations['LocationFeatureDescription'].'</li>';
} else {
$facilities = "";
$facilities .= '<li>'.$row_rslocations['LocationFeatureDescription'].'</li>';
}
// set $previous to current value for next time
$previous = $row_rslocations['LocationID'];
?>
then just add the $facilities string to the infowindow
