How to set variable from Firestore

Resolved

I've seen a few videos on how to do this but I keep getting stuck at "Available Options".

I have a collection which is straight forward it only has one field "category".

I go to my project which contains a list and individual buttons quering this data.

I click on Text as I want to set the text of the button to match the category name.

I select "category" as the individual field.

But then that kicks me into what appears to be an endless loop. It has me select Available Options, I select the following because it seems to be what I need but it won't display the variable. I end up with the last option on the screen in example [Has category Field]. I simplly want the category name.
