title: Permissions for functions in Spreadsheets
body: <p>I am using a new feature of SpreadSheet in Google Sheets: 
  "Named and protected ranges". In this range of protected cells, I use arithmetic built-in functions and my own written functions. 
  The trigger to run my functions is on edit spreadsheet.</p>
  
  <p>Users with write permissions, sharing the link of the spreadsheet, can't properly run my functions for permissions problem while built-in functions run properly.</p>
  
  <p>Own can I grant permissions for my functions to run as Google Sheets built-in functions.</p>
