Constraint in Survey 123, I want to constrain input based on previous question

[jasongraham]

Hello

I am using survey 123 connect.  First question is for example,  "How many people bought a fishing license in your household this year?"

Lets say the user enters 5

Next question is "how many people in your household fished this year?"

I want to constrain this to be 5 or less.

I have seen things like .+<{Q1A}  but that does not work

any help?
