Creating Forms to send to ASP.net database

I’m creating a website where on the first page, I’ll be using check boxes for the user to select a prize. I don’t know how to make it so that only one check box can be selected at a time.

AND After that the check box is selected, I need the info to be submitted to a database, which will include information to the second page they are taken to, where they will enter their mailing address and submit that information.

I kinda have an idea how to submit a form for the second page by putting this actionscript on the submit button and using Input Text w/ named VARs (for the form part):

on (release) {
form.loadVariables(“http://www.yoururl.com/page.asp”, “POST”);
}

But i’m not sure how combine the information (and do that check box thing that I mentioned above)

I know this is a long question, but I would be ever so grateful if someone could help me out :puzzle:
