I am trying to add in a discount in an invoice but I keep getting the message
"You must enter a number into this cell" when I type in the negative sign. I
have also tried to do a formula (SUM(1400-1846.25) and it still won't accept
the negative. The sheet is unprotected. How do I get it to accept negative
numbers?
