Sorry you are still having trouble with this. As Helen mentioned earlier, we have now released the new version of our Zapier integration to all users, and it should be much easier to set up what you are looking for there.
To clarify further, if you use any special characters like “-”, or brackets “()” in your phone number value, it will not go through to our servers in the old version. In order to use the newest features in the Zapier integration, you will just need to re-create your app and use the latest monday.com integration version.
In terms of the correct column ID to use, it should be “text0” as my best guess here, but without seeing a screenshot of the column ID, it would be hard to tell. The newest Zapier release will handle this one for you, however.
I hope this helps and I’m sorry for the frustrating experience.
