Crystal Reports field

There is a field jobhead.custname in the traveler, I moved it to a page
header so that it prints on every page.

I am trying to print the customer name on the traveller and it does print on
the '0' level job, but it won't print for the subassemblies... I have tried
to make another formula field = to customer name and then print that but it
still doesn't work. I remember seeing something like this on a thread
before but I don't remember the answer. Thanks to all!
