adding a variable to itself

2004-08-02 17:41

Hello..

 

This is an example of the subreport I desire.

 

Name Hours Amount Expense

 

RK 0.60 45.00 0.00

TW 25.50 1912.50 102.50

Totals 26.10 1957.50 102.50

 

I need to groupby name, add the hours etc. to get a subtotal per name and generate a final total.

I dont really understand how to make the group by work in iReports as well,

how do you keep adding the hours variable together to get the total ie. new Double($V{hours}.doublevalue) + ???????

 

Thank you

 

TB

Use a variable. The expression of a variable is evaluated on each new record.

 

Use builtin variable functions to perform sum or count.

 

Use a variable for the total (alias reset time = report), and a different variable for subtotals (alias reset time to group).
