interconnected pull down menu?

[peach255]

I have 2 pull down menus called "dept" and "discipline". I want the discipline pull down menu values to be dependent on the chosen values of the "dept". For ex., if dept=PRCL, then values for discipline= ACH, GEN, if dept=DISC, the discipline=CHM, and all else discipline=GEN .
I don't know how to write the syntax for this. This is what I have so far, which did not work, but instead display all of the values.
<select name=&quot;discipline&quot; id=&quot;discipline&quot;>
if document.all.dept.value=&quot;PRCL&quot; then
<option value = &quot;ACH&quot;>ACH</option>
<option value = &quot;GEN&quot;>GEN</option>
elseif document.all.dept.value= &quot;DISC&quot; then
<option value = &quot;CHM&quot;>CHM</option>
else
<option value = &quot;GEN&quot;>GEN</option>
</select>

Thanks!

Peach,

Have you considered this route:

Worked like gangbusters for my application!

You're not changing the values of the drop-downs, just having a separate drop-down2 for each possible option in drop-down1 and making 'em all invisible except for the appropriate one.

Cheers,


Edward
