Hello, I have set up an Expression Advanced Action to display the sum of 2 variables and it works perfectly. I now want to extend that to calculating the sum of 9 variables total. Is there a way to include all the variables in one row such as V_Sum= V_1+V_2+V_3+V_4 etc., or do I need to set up and action another way such as calculating the sums of the different actions?
You just add more line items that are Expression actions underneath the current one. Each line begins with the total from the previous line. The trick here is that you only add ONE of the variables to V_Sum at a time.
So it looks like this:
V_Sum = V_Sum + V_1
V_Sum = V_Sum + V_2
V_Sum = V_Sum + V_3
I personally find this easier/faster than clicking out nine expression actions.
Just don't forget the semi-colon on the end.
