Problem with a personalised Case Statement in Data Studio
we got a problem with a personalised case statement. In a Datastudio-Report, we try to sum up two variables imported from Facebook.
Somehow, when one of the variable is 0 (or "null"), in our Report there is displayed "null", even if the other variable has data. We tried to fix that problem with a case statement but Datastudio tells us that the formula is invalid.
Here you can see a screenshot of our formula. Could you please help us?
