Macropod, thanks for your last post. I tested out your new field code and got the result below:

FP-1 (FP-!Undefined Bookmark, PAGE+1} Blank)

My hunch is because the quantity of braces you have in the field code is 11. This does not allow for each brace to be paired with another brace. I tried making it work with 12 braces with no success.

As for your first field code that looks like this:
{IF{=MOD({PAGE},2)}= 1 "FP-{PAGE}"}

It works like a charm on my home computer. However, when I tried it out at my job site on the 600 page WORD file the field code does not work. I input it exactly as I did at home and when I hit F9 the field code does not output "FP-1". It outputs nothing at all. Not even an error message. So as a control test I opened a virgin WORD file. In the virgin file your field code works like a charm. So my conclusion is that my 600 page Word file at work is somehow corrupted and that's why the field code don't work. I tried an "Open - Repair" operation and still no luck. Tomorrow my strategy is going to be to open a virgin file and setup the field code and schematics as I need it. Then I'm going to cut and paste 600 pages from the corrupt file and cross it over to the virgin file. I hope this will produce some positive results. Any opinion welcome.

Thanks again for your last post.
