I am trying to get the financial calculation on this to trigger whenever there is a change to select1. Right now, the user has to click on select2 to trigger the changes.
Ideally, a change of select1
1. trigger the population of select2 (and set it initially to 0)
2. make the text fields disappear
3. trigger the financial calculation to reflect the select1 choice.
Any help would be greatly appeciated !

Heya, Greg.
First off:
[CODE=javascript]
JavaScript code goes here.
[/CODE]
and
[CODE=html]
HTML code goes here.
[/CODE]
and so on.
To answer your question, can you add the function call to the onchange attribute for your select element?
Hi
Thanks for the response..sorry about the code tags...thought I was doing it right....will do better next time :)
I am a newbie to javascript. The code I sent was written by somebody else who I paid a small deposit to write it but he never finished it completely. I was supposed to pay the balance when the work was completed.
I have tried contacting him but have gotten no response...so I am trying to get this thing finished and out the door..I am on a tight timeline for a project I volunteered to do.
How do I add the function call to the onchange attribute?
Sorry for all the newbie questions.
Thanks
Greg

Heya, Greg.
Oh goodie.
Alrightey. On this line here: -
<td><select name="category" id="category" onchange="PopulateSelect2()" >
-
you're setting the onchange handler to 'PopulateSelect2()'. In other words, when the selected value changes, the browser will automatically call PopulateSelect2().
All you need to do from here is create the function that does all the stuff you need it to and add it to the event handler, e.g.: -
<td><select name="category" id="category" onchange="PopulateSelect2(); RunFinancialCalculations();" >
-
That should get you started; we'll go from there :)
