How to disable textbox

[peteswrx]

I have a combobox that looks like this:
<select name = &quot;cboList&quot;>
<option>Not in list</option>
<option>Vendor1</option>
<option>Vendor2</option>
<option>Vendor3</option
</select>

I also have another textbox that looks like this:
<INPUT type=&quot;text&quot; name=&quot;txtVendorName&quot;>

I want to disable the textbox whenever the combobox does not = &quot;Not in List&quot;.

This doesn't seem too difficult but it's giving me plenty of headaches...

Much thanks goes out to anyone who can assist here.

<select name = &quot;cboList&quot; onChange=&quot;CheckOption()>
<option>Not in list</option>
<option>Vendor1</option>
<option>Vendor2</option>
<option>Vendor3</option
</select>


function CheckOption()
{

if cboList.options{cboList.selectedIndex).text==&quot;Not In List&quot;
then mytext.disabled = true
else
mytext.disabled=false
end if

}
just tweak this a bit

Thanks I figured it out. This seems to work pretty good...

<script language = &quot;vbscript&quot;>
sub DisableTextbox()
if document.Vendor.cboVendor.value <> &quot;&quot; then
document.Vendor.txtVendorName.value=&quot;&quot;
document.Vendor.txtVendorName.disabled=true
else
document.Vendor.txtVendorName.disabled=false
end if
end sub
</script>
