Google Site Apps Script

Question

I have created an approval workflow in Google Sites. When I submit a request to a manager.

He approves the request from the GMail Approve button, but it displays an error that he doesn't have permission:

I have shared my Google Site to him, and he can edit this Google Site:

But why couldn't he approve the request from the GMail Approve button?

I found that if I create a script from Google Drive, there is a Share button, but if I create Apps Script from Google Sites, there isn't a Share button:

How could I do this? How could the manager use this Google Site approval workflow?

Answer 1

How does the script run and who had access to it. There are 3 (or4) access levels for any web app - only you, anyone in the domain, anyone, anyone including anonymous. Have you set the appropriate access permission for your app.
