I am creating a PDF form where the user will be selecting from a long list of 25 options. The fields are radio buttons, with one choice for "primary", one choice for "secondary", and one choice for "none". There can only be one primary, but there can be many "secondaries. So the radio button groups are:
Choice1: P() S() N()
Choice2: P() S() N()
Choice25: P() S() N()
So I'm wondering if there is some way to make it so that once a user picks "P" on one of the choices, they can now only choose "S" or "N" on the other choices. Or even better, they can still choose all 3, but if they choose "P" on a different option, whatever option they originally set to "P" would automatically be changed to "S".
