Hi Tami,
I read the post and based on your previous conversation, I tested on my with the latest version of Current Channel (Preview) i.e. 2007 (Build 13029.20236) and I can use range in the mentioned functions (AND and OR) without any trouble.
Here’s a screenshot for your reference.
As your Office build is behind an update, please try updating Office to the latest version and check if you still get the same problem (your build is. To know how to install updates, see Install Office updates13029.20200 and the latest is 13029.20236)
If the issue persists after updating Office, please provide us with your sample workbook, so we can test with your workbook on our end and see if we can reproduce the issue.
To protect your privacy, I will send you a private message (pm) to collect the sample workbook.
Please click here to access pm.
Regards,
Neha
