Hi All,

I have two radio buttons in my report.

1) party wise report ( if R1 = X this will display report )

2) sales wise report ( if R2 = X this will display report )

i declared in report attributes as party wise report .

When i clik sales wise report.

it is coming party wise report,

i want it to be as sales wise report.

Please let me know how to do it.

Thanks in advance
