Access subreport variable from main report

2003-06-30 14:29

Hi, suppose I have the following:

Manirpt

Subrpt1

var1=sum(something)

Subrpt2

var2=sum(something)

 

Is there a way to make a variable from Mainrpt that would look something like:

var3 = Subrpt1.var1 + Subrpt2.var2

 

Thanks,

 

Julio Ortuzar

I too am faced with the same problem.

I have two detail bands (detail1,detail2) in my main report. They contain two independent subreports.

They both return two double values to the main report. This is hapenning properly. I know this because I can print them seperately in the column footer.

But in the column footer I need to display the simple total of the two. I.e. I have defined the $V{grandtotal}

varialble of which the evaluation expression is $V{var1}+$V{var2} where var1 and var2 are the variables that catch up the return values from the subreports.

When I print the $V{grandtotal} it displays null always no matter what I do.

Please help me with the issue as this is urgent. Any help is greatly appreciated. I am using ireport 4.0.2.

Thanks a lot,

Chaminie.

 I noticed one of the last properties of a subreport is return values.  I have you tried using that?

[chaminie]

Thanks for the suggestion.

Yes, I am using the return values and both my subreports return values to my main report properly because I print them in the main report.

The problem is with using a third variable to sum up the two variables that contain  the return values from the subreports.

It always yeilds null.

Thanks

When are you evaluating the new variable?

[coffee_keyboard]

 Try with Evaluation Time of the TextField where the third variable is used set to Report

Thanks for the suggestion.

I tried it but I keep getting the same null value.

Is there any other way?

Hi:

In ordere not to get the null u need to set calculation type=system for the variable which u created.
