I think you will personally find this a monumental undertaking.
The problem (correct me if I'm wrong) is that you do not 'know' any
ASP. You are not even a beginner as you have not (yet) made a decision to learn
ASP. You are using Macromedia products to build your code for you, and as such you will never really learn much.
ASP Code building tools are fine and dandy to speed up the process, but I never recommend them until you know
ASP really well. That way when things go wrong, you can sort them out. In parallel you can also accomplish things that your code building tool will not allow you to do (such as this problem you are facing). I would highly recommend you purchase a good
ASP book and crack on with learning some of the basics.
Conversly, I may be way, way of the mark here and I apologise in advance if I have judged your situation wrong... I think it's a combination of your use of code builders and the way you wanted to tackle this issue with two submit locations that leads me to believe you are not a coder.
If you are looking to learn
ASP, let us know and we can help you out and point you in the right direction. If you are just wishing to stick to code building tools, then I think you'll have to learn their use to an advanced level to solve this particular task.
I hope my honesty has not offended you.
