I'm writing a QF session where there may be 1-5 pages for that document class.  I want to get basic information of the invoice, account, date, etc. from the first page.  If it is the first page get the total amount due (note the format of each page uses the same basic fields-but only the last page (or first) will have an amount in the total amount due).  How do I use the Last Page Identification method to capture that information from page 1 or page 5?  What I was hoping to find is a way to use the IF statement that if this document has 5 pages.... then tell it to go to the last page to get the total amount due.  Any quick solutions?
