Conditional Formatting formula

Hello

I have attached a formula example.
I have this conditional formatting formula: =AND(ISNUMBER(C4:K4),ISNUMBER($L4)) when I put any number on cells C4 to K4 a soon as I put any number in cell L4 it becomes red.

I need the same formula BUT excluding number ZERO (0) All cells C4:K4 and L4 excluding zero.

Do I need a new formula to work with this one or can I use this one modified?
Anyone knows how to do it?

Many thanks in advance.
