About two years ago I created a sheet with some buttons with some code. I just recently wanted to work with it again, and all of the buttons are disabled, and I don't see the code I used for the buttons. How can I "reactivate" my code?
I know there was "script" there before, but when I click on the 3 dots, and "assign script" nothing shows up.
Have you tried going into Extensions > Apps Script yet? In there you should see your custom script code. Once in there, you can check to ensure your code is all correct.
The next time you left-click the button, the function should run. You may need to authorize the script, then run it.
