I am fairly new to Actuate. I am working on a report that has 12 fields (ETC1-ETC12) I want to add them together, then subtract ETC. Only problem is that there are NULLS in say ETC7-ETC12 because no time is recorded yet. How do i write either a SQL code or Function to handle the NULL values. Also how can i make it so there is a variable called [Var]and it is the SUM of those ETC1-ETC12 fields. Thanks so much.
