Also a good point. Many people alter the HTML File (keeping in mind you'll need to re edit each time you change the form in the program). You can add add a link to your Terms of Service or whatever they need to agree to right on the HTML file. So you can add a check box with the program, then edit the HTML File when you're done with the form and add a sentence with a link to your TOS so people can go read it before clicking the box. That would most likely take care of what you need all the way around.

We have had the two forms on two seperate pages for several months but for some reason, no matter how we word the instructions, people are just not submitting the second form even though they have been redirected to it. The idea of putting both forms on the same page with the second one only showing when the first one had been submitted seemed to be the answer but as Scott says it's not possible to do, we will go back to the drawing board and see if there is any other way. Unless you have run a dog rescue where specific agreements and information is requred, it's difficult for anyone on this forum to understand what we are trying to do (no offence meant). We are dealing with the rehoming of dogs that may have been ill treated so we have to get things right.
Thanks for all the suggestions.

Have you given any thought to doing a redirect to the next form but change the text on the submit button on the first form to say something like on to next section.

It's an idea, Eric. I will give it a try.

Another option would be to have a popup script show when they land on the redirect page reminding them to finish filling out the form. I did that with Colorbox on my moms website to let people know we were full for a particular weekend. There was a huge concert at a local venue and we were getting swamped with calls. I put the popup on all of the pages that had any contact information on it. It worked well. We went from 50-75 calls a day down to only 5-10.
