Problem with parameter from subreport

[llaconde]

Hello i'm using a subreport in my main report and I get back a sum from this subreport. It is called Somme_Surface_Parcours_2. I have to add this variable to another variable: Somme_Surface_Parcours_1. I need to put this addition in another variable: Somme_Surface_Parcours in which i put this : "( ($V{Somme_Surface_Parcours_2}==null) ? $V{Somme_Surface_Parcours_1} : $V{Somme_Surface_Parcours_1}.add($V{Somme_Surface_Parcours_2}) )"

 

If I try to display this variable, i only get the Somme_Surface_Parcours_1 but if I display directly in a field my expression, it works just fine.

So I really don't understand why something that is working in a field doesn't work in a variable.

Please, help me, I going crazy!!!:woohoo:

I forgot to tell that I'm forced to use a variable because I have to use it in a group after..:pinch:

Try setting the Calculation Type for the variable to "System" and see if that helps.

I tried but i get "null" as result.

 

Do you anybody have an idea?

 

Thank you for your help.

I still haven't found the solution.

I have same problem and I resolved problem with directly sum variable in text field (not use variable in master report).

By my opinion maser variable calculate before get variable from subreport and because you have always only one variable added in master report sum variable.

This is really unfortunate because in many cases you are going to want to use a variable to sum the addition of two subreport variables in the master report. Using the text box technique you can get show the value of the subreport band but you can't perform any summary operations.

I should note the scenario would be like this

MasterRep1Var1 =SubRep1Var1

MasterRep1Var2 =SubRep2Var1

 

The following can be done using a text box

MasterRepTextField1 = MasterRep1Var1 - MasterRep1Var2

 

However if you then wanted to sum all of the differenences up for the master report you would not be able to.

MasterRepSum(MasterRep1Var1 - MasterRep1Var2)

 

Sincerely,
