Advanced Form solution pack Modification

Hi Guys and thanks in advance for your help.

Here is what i am trying to achive.

1. Form to open in thick box. (got that covered)

2. First part of the form will require client to choose one check box from three options.

3. Once a check box has been chosen the content output to the remaining form will have different questions shown for the client depending on her first check box choice. For example

If client one chosed check box 2 her questions would include such things as , name address, email, phone number, but if she chose check box 3 further questions would be added to the form such as business name, website etc. as well as the form options for check box option 2.

I must add that this is not something i have started yet but would love to know if anoyine out there has either done this and can give me instructions or if it not been done yet maybe some can still point me in the right direction.

I hope that i have made it clear, please feel free to let me know if you need more info.

Thanks again in advance
