ClearCollect returning one of 90 items

[notj]

I have a label with Text set to: 

CountIf(FacAppCapBudget, budgetYear="2019")

Result: 90

I have a button OnSelect set to: 

ClearCollect(CurrentFacilityBudgets, LookUp(FacAppCapBudget, budgetYear="2019"))

Result: 1 item, which would be the first item alphabetically. 

What am I doing wrong here?

LookUp() only returns the first result. You want to use Filter() in this case.

Thanks. I've used Filter 20 times now and I suppose I just had a brainfart putting this together.
