thanks for the answer.
not 100% what i intend to do (i think he wants to tick on a diagram and then automatically have a checkbox ticked or vice versa) but i think i might get some hints on how to proceed and how big the effort would be.
What a coincidence, I just got back from a visit with my implantologist.
With regards to the graphics display, what you want to do is doable in FMP. Doable but tedious. 160 container fields (32x5) and 160 number fields to keep up with where that part of the tooth is color wise and one repeating global field with the colors you want to use. A script or two to set the container fields, and you would be good to go. Make each container field a button that runs the color selection by number of clicks.
Combine that with what ever text fields you want and you would have a shooting solution.
Email me if you want a copy of the quickie test file.
