Save a drowning woman PLEASE!!! Taking over for a guy who is gone but not forgotten and am completely GREEN!

How to???????

A. Can't seem to get totals when closing cash drawer to print on receipt, even though I've entered Emp ID#, cash drawer password, and invoice #'s, = register difference of whatever cash entered.

B. Is there a way to print inventory record of what has been sold per cash drawer close-out?

THANK YOU THANK YOU for ANY help!
