I'm relatively certain that a similar question has been answered previously,
but am in a pinch, and really can't take time to read a bunch of posts.
Hoping someone can help.

Spreadsheet A2:N56 = data about transactions (each row is a different
transaction)
Column L indicates "Shipping Date"
Column O =NETWORKDAYS(L2,$P$1)-1
P1=Today()

Desire to highlight entire row if O2:O56 is equal to or greater than 12.

All help appreciated!

TIA,
Sandi
