Hi Shane,
That's a big long script you have, and I'll be the first to admit I'm not a JavaScript expert, I just have an understanding of the basics, just like I do with Perl!
As far as I can see, there's two ways you can go about this, and I'm not sure about either.
I'll have to have a look through the WebReference article for more detail on how it works, but I'll give you an idea first, you might be able to figure it out yourself.
My fist suggestion would be to add hidden fields to the third form, with the names of the fields from the other two select boxes. When the script operates normally using onChange, have it pass the value of the fields into the appropriate hidden field in the third form.
The other way to do it, would be to have all the fields in one form. I know you tried this already, but you probably didn't modify the script to match, therefore the script is trying to access forms that don't exist and is confusing its elements.
I'd be inclined to go for the first one, it'll probably require less modification. I'll try and have a look over it later today, but have a go off adding the first one yourself.
In the relate function, try something like:
Code:
var Field1Value = document.forms[formNum].SelectedIndex.value;
document.forms[2].Field1.value = FieldValue1;
... which, if the first hidden field in forms[2] (the third form) is called Field1, will set that field to the value of the select item you chose.
All pretty vague I know, but I don't know enough about the script to be more detailed.
