Count records with Null values

[mchambers]

Hello,

I am creating a report that shows all staff productivity for each individual day of the week there are some staff who show a zero on some days and I can’t get the grand total at the end to count the staff Member if productivity is zero. Any help is appreciated. Here is the expression I am using.
=sum(Fields!Duration.Value) / (count(Fields!v_PROVIDER_NAME.Value) *8)

Thanks

The general way to 'count' values that are null is by using a case statement

I.e., sum(Case when field is NULL then 1 else 0 end)

I hope this helps.

Thank you for your response. How would I do this in SSRS under the expression? Sorry new to SSRS. I have attached my sample data and groupings.

If I recall correctly it would be something like this. =SUM(iif(ISNOTHING(FIELD),1,0)

I change it to =sum(iif(isnothing(Fields!Duration.Value),1,0)) / (count(Fields!v_PROVIDER_NAME.Value) *8)
and all zeros came back.
