Envelope Budget Scripts Not Working - adjust cell and dropdowns stuck

Glad to hear you fixed it, @matthew.fuller526.

As for the Savings Budget, the main advantages are that it is more performant, less dependent on scripts, less brittle, and built to better integrate with Labs and the latest templates. All that said, if you are getting everything you need out of your current spreadsheet, there is no rush to make the switch. Just wait until something breaks or you are no longer happy.
