Simple question, but I can't figure it out.
In the spreadsheet above I have a table in A1:B5. I have a filter in A7 and its value is an array.
In A11, I want to textjoin all the values of the filter results (so it should be "A,C,E"), but I can't figure out how to do it. It seems like the reference to A7 just returns the first value. How do I reference the whole array?
