When the add-on is not activated or the Google Sheets is not recognizing our add-on, you get Unknown function error #NAME?

such as:
Unknown function: ‘GORILLA_SKUFNSKU’.
Unknown function: ‘GORILLA_SALESTOTAL’.

To fix this:
1. Activate the add-on, add account ID, and seller ID (in the inputs tab) and the data will start populating.
2. If you have already tried the 1st step and still can’t get rid of the error, then it means that Google Sheets is not recognizing our Add-on and you have to create a copy of your spreadsheet and then do the same steps as mentioned in the 1st step.
