I'm getting this "Operator or expression '()' is not supported in this context." I'm not sure why

[Anonymous]

So I've got a SUM function that adds up all the hours in the LineItem table. That is then filtered by a StageLabel text which is "Booked Schools" which is from another table called DealPipelineStage, here is what it looks like below:

Delivered Hours = (SUM(LineItem[Hours]), FILTER(DealPipelineStage, DealPipelineStage[StageLabel] = "Booked Schools"))

However, I keep getting "Operator or expression '()' is not supported in this context." and I'm not sure why, I've tried to change up the brackets but I've still got the error, does anyone know what the problem could be here?

Add a calculate before the sum

Ahhh thank you @Anonymous so calculate is needed for two seperate functions? I appreciate that.
