Thanks, I didn't know I had to use the 'field' function. Although the description in the reference section of the manual doesn't sound like how you described it (getting the value from the metadata field).

Finally, if there is any chance that the #chapters field is empty (zero) then you need to test for that before doing the divide.

Although, I try to make sure that empty chapters fields get a 1, the last code you gave me works perfectly.
Thanks.
