PowerApps button doesn't run Flow to execute a Stored procedure

Question

In PowerApps I have a canvas App with a button. The action is to run a flow. The flow is to run a stored procedure with 2 parameters to update a table. The Flow works (at least the Flow Test worked).

The OnSelect action is ProcedureFlowName.Run(Id.Text, NewID.Text)

ID and NewID are labels that hold valid ID numbers. The flow has the 2 parameters set to Ask in PowerApps.

So I run the App, click the button and then check in SSMS, no update performed, but the update does happen running the Flow Test.

I am admin or owner for the App, Flow and Database.

Any ideas?
