VAR formula error

There is several errors in your formula - parenthesis in wrong places, and your first FORMAT is missing a second parameter. I have cleaned the parenthesis, but you still need to change your FORMAT to what ever you are trying to do.

LocationCounts =
VAR Final_Total = 
IF(
	CALCULATE( COUNTA(Case_Data[Location]) ) = BLANK(),
	0,
	CALCULATE( COUNTA(Case_Data[Location]) )
)
VAR Current_Category = 
CALCULATE(
	SELECTEDVALUE(Case_Data[Location]),
	ALLEXCEPT(Case_Data, Case_Data[Location])
)
RETURN

IF(
	Current_Category = BLANK(),
	FORMAT(Final_Total), 
	FORMAT(Final_Total, "0")
)
