Calculate percentage of Users

Good afternoon

I need to calculate a percentage from different types of users in a Lookerstudio dashboard. I have to compare the page visitors of a certain page with the users of a chatbot on the page and thus calculate the percentage of how many of the page visitors use the chatbot. Unfortunately, I have not been able to do this in several attempts - it would be great if someone could help me here!

Here’s what I’ve done so far: I have created a calculated field for the users of the page as well as for the users of the chatbot.

I then calculated the percentage from the two values:

But the calculations/fields don’t seem to be correct - the numbers don’t match the user numbers from Analytics.

Who can help me? :folded_hands:t2:
I have also set up 2 audiences in GA4, which could be used if this is easier.

Thanks a lot and kind regards
