Printing the form but only the header prints

[Pauly78]

I have a couple of forms which i use as a receipt to give my customers, i have 4 different formats depending on the item the customer has. The problem is, 2 of them will only print the header and i have no idea why! the other two print absolutely fine. Is there a control or setting i need to be looking at because im absolutely baffled!

Thanks for any help

do they show up in print preview ok, but don't print. Or is the data missing in print preview?
Is the report based on a query? If so, does running the query make the data available to be printed?
Is this 4 different reports, or 1 report?
