Hi
I want to build a cross navigation report using BIRT. I have created a master report “Parent” and a child report “Child”. I want that if click on Customer name, it will open the child report. Under properties editor window, I selected Hyperlink and changed it according to fig 1:

Then I have created a "Child" report. It’s data come from this query:

Then I’ve created Report parameter “pcustomer” and data set parameter ”param_1” as below


Then I created an analytical Driver with manual input that it’s lable is “pcustomer”. So I have modified the “Child” report and selected the analytical driver such as below:

For “Parent” report I have created an output parameter called “LCUSTOMER” of type string.
At the end a cross navigation have been created:

But when I have run the "Parent" report an click on customer names, It cannot navigate to Child report and nothing changed.

please help me.
