Maybe I didn't describe the problem clear enough..
Here is how the site will look.
Navigation: Models / Talent / About / Contact
Clicking on the models tab would open up a new page with thumbnails of each model, then clicking on the thumbnail would take the client to the model's profile, (Home>Models>Amy) where I would want the "select model" button/check box to be. Then client can navigate back to the thumbnail page and click on another model's picture and go to that profile, and select another model (Home>Models>Katie). When finished, client would click on contact (Home>Contact) and see those selections in the form, and continue to fill out the rest of the information and submit it.
There would be a need to store the "selection" somewhere and that's where I'd like to maybe use a script or code. Don't know how to do this. Also I don't know how to feed that information to the form.
