Google Sheets - Script function could not be found

Question

I am working to link an image in my Google Sheet document to a specific cell in another tab. I'm doing this by building a simple function that will do this. However, when I assign the function and then click on the image, I then get the error "Script function "test" could not be found". When I run the function in the script manager interface, it works fine. It's when I try to actually use it in the sheet with the image.

Function Script:

function test()
{
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("TX Marketing Data");
  sheet.setActiveRange(sheet.getRange("A91"));
};

Steps to recreate:
1) Create image
2) Go to image, right click, go to drop down and select "Assign Script"
3) Enter "test" as the assign script

Answer 1

Remove ";" at the end of your function (after }).

Answer 2

Try reloading the page.

Sounds like a simple 'turn it off and on again' fix but after having the same issue and trying to save a new version, renaming the function, creating new function etc. a page reload was all it took!
