I have a report expression with a UDF in the group summary band which uses the sum feature to calculate total board feet for the group. I also have another expression in the group summary band using the sum feature to calculate total sales for the group. I want to use these two totals to calculate average sales/1000 bf. I have tried using report variables to store the totals but I always get an eror saying it can't find one of the fields required by the UDF when I do this. Is there any way to access these two calculated totals so I can use then in another expression?
