How do I use multiple fields to conditionally populate another field

I have a form that will be used for baseball registration, the user will enter the child's gender and date of birth. The form already calculates the child's age automatically.

What I am trying to do is take a combination of the child's gender and their age to create an output field that will display the division they will be placed in.

EX:

if gender = male and age = 9 then output would = 9/10 baseball

if gender = female and age = 12 then output would = 11/12 softball

There will need to be many different outputs based on the gender and age, but was unsure how to accomplish this (I would normally say using a case statement, but didn't know if that was possible)

Please test my form https://form.jotform.com/61678860212963

It work like this...

The Conditions I created is like this

As you can see, you can use Update/Calculate field values to achieve population of a field base on different/multiple fields value.

You can clone the test form also so that you can review it on your Form Builder.
