Format a cell based on values in that row

[ghladik]

Column B contains the individual cells I want to color if there is a "2" anywhere in each of those cells rows. For instance, if row 20 has a series of numbers, but not the number "2", I don't want it colored. If row 21 does have a cell in that row with the number "2", I do want it colored.

I attached a photo illustrating this. My problem is I can't find a way to set the conditional formatting in bulk. I can do it if I want to duplicate the rule 5 million times, 1 per row.

Any help is appreciated!
