Thanks! This is starting to make sense...although when I try to
reset what I thought was my array, I get the "Variable passed to
reset() is not an array or object" error message. Here's the
relevant code:
$relationsquery = "select * from relations where
childtype='$childtype' and parenttype='$parenttype' and
parentsku='$parentsku'";
$relationsresult = mysql_query($relationsquery) or die(mysql_error());
while ($relationsrow = mysql_fetch_array($relationsresult)) {
$thischild = $relationsrow["childsku"];
if ($thevalue == $thischild) {
echo " checked";
}
} // end while for relations loop
reset($relationsresult);
Thanks again for your help so far!
