Crystal Reports: sub report parameter

I have a report where the user types in an invoice number to retrieve the data.

Because the report has a Sub report attached the user has to type in the same invoice number twice. (See attached)

Is there any way I can use a single Parameter for both reports? User generated image

Thanks! it works after fiddling about with the links a bit!

I had to link Tinvoice to Pinvoice and select sub report parameter: ?Pm-Tinvoice

Tinvoice=transaction
Pinvoice=payment

Not sure what the ?Pm bit means though
