I need the form to work when
a groupName is selected to popualte the listbox with values.
If the GroupName is not selected then Do not populated anything for the listbox.
Please help Thanks

I think you will need to use something like <select name="name" 'onFocus="PopulateListBox()">

You will then need to write the PopulateListBox() function to do what it says.

Actually, thinking about it, you may need to put 'onClick="PopulateListBox(var)"' in each of the <OPTION> tags.

var is a unique variable which can be used to determine the values to appear in the listbox.

To add to matty's post - i would suggest using onchange in the select tag as the event handler, also this is a javascript question, try the javascript forum
forum216

and I have written a faq about dynamically changing select boxes.
