what Terri could so is query the DB on loading the page, then validate the
answers with a simple JS function.
<script Language="JavaScript" type="text/javascript">
function Check_Items(Item1,Item2){
if (Item1.value!=Item2.value){
alert ("These contradict the DB")
Item1.setfocus();
}
return;
}
</script>
then in the page
<input type="text" Name="MyInput"
onblur="Check_Items(MyInput,#Db_check_Item#);">
this should work, you might have to wrap round a CFOutput, round the Input
tag.
In theory it should work, give it a try and let me know.

But Terri wants to compare the client-side form element values to what's in
the
db. In order to do this, she'll have to get the db info into JS. She could
query for the data and then convert it to JS via CFWDDX ACTION=CFML2JS.
