Checkboxes and ASP

[smellykat]

I have a table with 2 columns: Vendor Name(display only), Transactions(checkboxes). The amount of checkboxes and their values vary depending on who the vendor is.
For example:
Vendor A name=checkbox value X
name=checkbox value Y
Vendor B name=checkbox value X
name=checkbox value Y
name=checkbox value Z

What i need to do when the NEXT button is clicked from that page is update my database according to the checkboxes selected. The problem is that the value in 'checkbox' is a comma-delimited list of all the ones checked, regardless of which vendor it is. So i would get X,X,Z...How do I know what vendor it goes for?? How can I read the value in the checkboxes correctly?
I am using ASP and Javascript.

Thanks.

You need to set the name to something specific for each vendor. Something like this:

Vendor A:
<INPUT type=checkbox name=VendorA value=X>Item 1
<INPUT type=checkbox name=VendorA value=Y>Item 2
Vendor B:
<INPUT type=checkbox name=VendorB value=X>Item 1
<INPUT type=checkbox name=VendorB value=Y>Item 2
<INPUT type=checkbox name=VendorB value=Z>Item 3

This will give you two different Requests: VendorA=X and VendorB=X,Y,Z.

I hope this helps. Einstein47

Ok, that helped, somewhat. Thanks.
Now for my next question: On clicking next, I need a javascript function that will loop through each vendor in the table, and make sure that at least one checkbox is checked for each vendor. So if there are 4 vendors selected into the table by the user, then at least 4 checkboxes should be checked, but more is ok.
