Value field in a Radio Button

I am adding a Radio Button to a form. It has the standard Choice 1, Choice 2, and Choice 3. I place the numbers 10, 20, and 30 in each of the value fields associated with the choices. I then add a Summary field and set it to display the Radio Button field contents. When running, I select Choice 1 and the Summary field displays the text “Choice 1”. Similarly for Choice 2 nd 3.

I thought the Summary would display the associated value of 10, 20, or 30 depending on the choice made. Obviously, I’m wrong. That’s not the first time something like that has happened.

I wish to set a numeric value depending on the choice made for further calculations. Is that possible, and what is the purpose of the value field if not to contain a value to be returned when its associated choice is selected?

Thanks… (a very puzzled) Tom.
