I have two select pulldown lists. What I'm wanting to do is when you choose something from the first list, the options of the second list changes according to what you chose. How is this done??

I'm pretty sure it is possible, but I'm not quite sure how to code it. There are a few people here that have more experience in the form area that should be able to help out though.

Hmmm, I saw this done on the link exchange site when signing up for the banner service - take a look at that and see if that is what you need...

This link demonstrates a pulldown with a select box:

Here is a script that will change the names and the values. You setup the values in the following arrays.

var newSelectionName = new Array();
newSelectionName[0] = "NAME1";
newSelectionName[1] = "NAME2";

var newSelectionValue = new Array();
newSelectionValue[0] = "VALUE1";
newSelectionValue[1] = "VALUE2";

function changeSelections() {
document.FORM.SELECT.options.length = 0;
for (i=0; i<.newSelectionName.length-1; i++) {
eval("document.FORM.SELECT.options[" + i + "] =
new Option(newSelectionName[" + i + "],newSelectionValue[" + i + "])");
} document.FORM.SELECT.options[0].selected = true;
}
