Finally got it to work. But why doesn't DataAssist search create dynamic radio groups? I tried using it, and all I got was static radio buttons, which I would have needed to populate manually.
<form action="sresults.php" method="post" name="sform" id="sform">
<table width="600" border="0" cellpadding="5" cellspacing="0" bordercolor="#ffffcc">
<tr>
<td width="147" valign="top"><div align="right">Select your Fruit</div></td>
<td width="427" valign="top">
<div align="left">
<?php do { ?>
<input name="fruitID" type="radio" value="<?php echo $row_getFruit['fruitID']?>" />
<?php echo $row_getFruit['fruitName']; ?><br />
<?php
} while ($row_getFruit = mysql_fetch_assoc($getFruit));
$rows = mysql_num_rows($getFruit);
if($rows > 0) {
mysql_data_seek($getFruit, 0);
$row_getFruit = mysql_fetch_assoc($getFruit);
}
?>
</div></td>
</tr>
<tr>
<td valign="top"><div align="left"></div></td>
<td valign="top">
<div align="left">
<input name="submit" type="submit" value="submit" />
</div></td>
</tr>
</table>
</form>
