I see how to set this with JavaScript. Can I pass the results of a
PHP query into a javascript? Something like this?

while ($row = mysql_fetch_row($rs) {
echo "<input type = radio name = radio1 value = '" . $row[0] . "'
onclick = 'fillTextBox(" . $row[0] . "," . $row[1] . ")'>";
}

and then have a JavaScript function something like:

function fillTextBox(var cat, var dbData) {
document.getElementById(cat).value = dbData;
}


THanks.
