Hi,
Display the signatures in the following way:
1) Create a secondary window below the main window to display "Prepared By" and "Signature".
Put one condition "not on last page".
2) In main window, create footer at table with conditions at end of table to display the same. Don't forget to page protect the "Prepared by" and "Signature" by inserting the nodes inside a folder and ticking "Page protect".
Regards,
DPM
