Hello Guy
Thank you for your quick answer.
Your suggestion works, but i have to store the result in a variable, because i have to print the barcode twice.
First with speciall barcode font and additionally "human readable" with normal font.
I can't call f_fetch_barcode twice because then i would get another number.
So i need a variable that is filled with the result of " f_fetch_barcode" on every new page and i don't
know how to code this.

Best regards
Albert
