How to set the Printing Range of an report

i am using the CrystalReport control in my vb6 form to open the report.

I want to know how should i set the printing range of an report
i.e print only from page 2 to 3 , or only page 2

i tried this , but its isn't working

Code:

crp.PrinterStartPage = Me.RangeFrom.Text crp.PrinterStopPage = Me.RangeTo.Text

Plz Help

Edit:
I found that it is printing within the range if the destination is printer else it is showing or exporting the whole report
