/

Hi @dylang91
How are your numbers weird?
IFNULL returns the second parameter if the first one is NULL. This means you're subtracting NULL -
CaseSubmissionDate
which equates to null. NULL / Number is also NULL.What you'd likely want is something like this where you're calculating the value if it's not null:
AVG(`FirstSetupApprovedDate`-`CaseSubmissionDate`)
AVG excludes any records which are NULL from the calculation and if FirstSetupApprovedDate is null then your arithmetic operation equates to NULL.
I'm not sure what you're trying to do with CaseID in this formula. What does CaseID represent?

Your syntax in your numerator is missing the "case" and "end".
I think you want:
(case when `FirstSetupApprovedDate` is not null then
FirstSetupApprovedDate`-`CaseSubmissionDate
end)/
(case
when `FirstSetupApprovedDate`is not null COUNT(`CaseID`)
end)

@GrantSmith thank you I didn't know that average will exclude the null.
