Gift Certificate Sales & Redemption tutorial

HI i followed the Gift certificate tutrorial,after purchased a a gift certificate,
1.it didnot print the GC20 number on the reciept.
2.cannot find in the search results

Was it this one you followed:

First thing you should do is go through the entire tutorial again and look for spelling and capitalization errors. (that is usually where mistakes happen)

Did you create a text line for a text file? If so, was anything recorded in the text file?

yes,that was the tutorial .i will go through again and come back to you.Thanks for your reply.
Thanks
