I have seen on different sites where they have their form set up in steps.
Basically what I would like to do would have the first step of the form where the user has to select an item to purchase. Once they hit the submit button(next button or whatever) it will check for errors of required fields and if everything is okay it will redirect them to step 2. Otherwise it will spit out the error on the same page.
I will have about 4-5 steps before sending them to the secure site to get their credit card information.
How can I do this?
thanks
