Awesome Jeff! Much appreciated. Have a lovely day
There are two relations in the Students sheet of the app. The original one and one that I created. Here is the url: https://tr0uy.glideapp.io/
This is the original one that @lancscheese created and I suspect was renamed after being created.
When attempting to create a Rollup against the relation, the Done button is disabled on nothing shows in the column for counts.
This is the relation that I created and set the name on creation without later changing it.
When I create a Rollup against my relation, the Done button is enabled and you can see that counts are showing.
