Ohk sorry got that 
thanks a lot for the help...
now can you please help me in another problem?
In the invoice that I have created the header has page no and reprint option. the requirement is that reprint wont be printed if its value is 0. so I have given a condition in the condition tab of the node where the reprint is being printed as GV_REPRINT not equal to INITIAL.
But this works for some and doent work for others.
Please help
regards,
Tina
