If/Then Multi-cell Conditional Formatting

I have an interesting problem on my hands. I work for a gas station, and for our cigg orders, we fax an excel speadsheet to SAMS CLUB. I recently have done some modifications by applying conditional formating to indicate negitive numbers and zeros, however, I am trying to find a way to blank out 2 adjacent cells when a cell = 0.

Here is a sample:

Order# Desc #to order

921934 (brown) Bx 0

The Zero is already whited out in my sheet, however I am trying to find a way to make the Order Number and Desc. be whited out also when the Number to order = 0
