Conditional record Numbers in Crystal report

I have a conditional detail section where the condition is : Suppress if Qty = 0

The output I get is as below:
Record Number .....Description .....Qty
1............................. pencil .............3
3............................. pen ................5
4 .............................eraser ............1
.
.
.
Due to suppress condition in detail section the record numbers are not printing properly.

Any work around on the above.
