I have a button for a script that takes the user to a layout (for use on iOS or macOS) that presents a value list as 100 radio buttons in a second layout. I want the numerical value of the radio button (1-100) in that second layout to be used as the value for a Find that will take the user to that record number in the original layout. It would accomplish the same thing as a Find where the user would type a value from 1-100 into the field but be mouse/touch based. I am not too with variables (concept but not syntax). Is the radio button value already stored, or does it need to be captured? FM 19 on Sonoma.

If you are using Filemaker's native radio buttons, then you are using a field formatted to display a radio button set. The user's choice will be stored in this field. If the field is defined as a global field, then its value will be available from any context.
