Change radio button value from another radio button

I have a radio button(R1) field in a form and another one(R2) in a subform. I want R1 to automatically change the value when I choose an option in R2.

Let’s say

R1

*Morning

*Afternoon

*Evening

R2

*Breakfast

*Lunch

*Dinner

I set Evening for R1 and when I set Breakfast for R2, R1 will automatically change to Morning.

Without more specifics, I am going to assume that your question is for a Notes application. The following is the simpliest way of doing it with application development:

  1. Enable the field properties (second tab), “Refresh fields on keyword change” in your R2 field.

  2. Put an input translation on R1, that does @if(R2=“Breakfast”; “Morning”; R1)

(There are also similar, arguably better, ways in LotusScript or JavaScript.)
