Hi Lise , Best option would be to create the roll up field and store the count in the account entity. With this, you don’t need to do any calculation on your end. Define rollup columns with Power Apps – Power Apps | Microsoft Docs Then you can add the field to the form and view you need, save and publish all customizations. Test: Note: Rollup field calculated periodically so you won’t get the exact count unless the field is update so in this case, you can use the workflow tools step to force the calculation.
