Total error on sub-group using evaluationTime

[mermaidtide]

Hi,

 

I have created a report which is divided into 2 groups: Customer and Invoice

For 1 Customer I can have a number of invoices and against each invoice I can have multiple payments.

Somewhat like

Customer1

                        Invoice 1 Amt

                                                         Payment1

                                                          Payment 2

                       Invoice 2 Amt

Now I want invoice total for each customer (Payment total was quite easy for each customer)

I am doing reset Type=Group and Group=Customer

evaluationTime=Group and Group=Invoice for this. I fail to understand what I am doing wrong. Please help me out on total evaluations. Have been using iReport since a week only so please pardon me if this is a silly Q.

 

Regards.
