Forms with active/inactive check boxes

[mbarbu]

OK, I'm looking for a script. I have a form with a list of titles. Each title has a check box next to it. Below this list is another list of titles with check boxes.

Here is what I'm looking for. I want the second list to be inactive until a certian check box is checked in the first listing.

If you have a script like this...can I please have a copy.
If you know of a place I can get this script...please do tell.

THANKS

you can do something along these lines.

suppose you have a checkbox name="flag" and if this box is checked you wnat to show another element name="phone"
then this is how it will work

if(document.formName.flag.checked){
document.formName.phone.visibility="visible";
}

the above will work if the phone element has visibility set to hidden to begin with.

Tried that and I got an error
Error: document.formName.flag.checked' is null or not an object

This is what I'm currently using and it works for making then disabled checkbox enabled when the "bSoftmed" checkbox is check...but it stays enabled even when I uncheck "bSoftmed".

<form action="_infoprocess-access.asp" method="post" name="AccessForm" id="AccessForm">
<script language="javascript">
function enableField()
{
document.AccessForm.strSoftmedApplications1.disabled=false;
}
</script>
<input type="checkbox" name="bSoftmed" value="1" onClick="this.value=enableField(this.form.strSoftmedApplications1)">
<input disabled="true" type="checkbox" name="strSoftmedApplications1" value="ChartFact-Locator">
</form>
