Skipping fields in a request object?

[Tim Chmielewski]

As it helps me with my coding I have been writing out the general steps
I want to do in plain english before writing ASP.

The values come from a customised data grid (not in .NET) that is
generated according to what fields need to be recorded for that record.

What I want to try and do is as follows:
- Read form fields into input array (skip first three values :
savevalues, userid, productcode) - Save last value of every row (add to
quantity for extra info) - rest of processing

Is the first one even possible using plain ASP? I remember being able to
do it using Javascript, but I couldn't get it to work properly.

I have tried to use Arrays in ASP before, but without much success.

Thanks.
