Hi all,

I want to compare values selected from a DE in a repeatable stage and show warning if they are different.

In the repeatable stage, I have a DE vaccine name with options IPV and OPV. If the vaccine name the user has selected is not the same as the previous vaccine name the person received a program rule should be triggered. The program rule does not work.

First I have created a program variable vaccine name

And a program rule

The vaccine name selected must be the same for all visits. there are five visits
