Countifs with or condition

Hi Experts,

I was wandering if there is any other way to use the below mentioned countifs formula as it's giving error result.

Basically, i want to count if x value is in column B:B and z value is in any K or L or M or N or O or P or Q or R or T columns.

Formula:

=countifs(B:B,x,K:T,z)

The attached file is for your ref plz.
