OK Kdriscoll, I see what you mean. I must set the field type in the form as HTML Editor, and then the multi line works fine in the PDF report. That is great for fields like terms of payment, or a footer, but to enter an address in a HTML Editor does not not very good. I may just have to make the address into multi fields and then make up a HTML string after I retrieve that address into the PDF report and allocate it to a local multi line field for display.
Thanks for your help.
PS. apologies if I seem to have gone to great lengths to explain this - but I might need it as a reference again in the future
