I want to replace the default format for cell d18 with a custom label of
"Customers", I know i need to use the quotation marks around Customers but i
am unable to get it to work.

here is a sample of what i'm working on

$255 $20 $21 $22
10 (2,145) (1,845) (1,545)
12 (1,905) (1,545) (1,185)
14 (1,665) (1,245) (825)
16 (1,425) (945) (465)
18 (1,185) (645) (105)

I need the 255 to read customers in stead of reading $255( that cells
formula is =b22)
Can you help?
