I found out with using bubble, I’m really bad at setting with database… 
I tried setting the [input data type] on the data source of RG, and then “Parent group thing”, “Search for [input data type]”, “Search for [input data type] :item# something”, “Search for [input data type] :filtered something (I don’t know but click and click)” to the Fruit dynamic text area on the user card, but it shows like the image above or nothing.
Probably it seems to need specify Fruit or Animal data from the latest thing user added (inputed on the user page). What and where should I do for it?
