How to count cells from last word in row?

Hi everybody, I'm new here and I'm from Croatia.

I have one question.

I do some statistics and I have rows like this: (with "" I'll mark blank cell)

A B C D E F G H I J K L
1 no x x "" x no x x "" x x x
2 x x x no x x x x x x x x
3 x no x x x "" x x x x no ""

So my question is: What formula is for count, in every row, just cells with "x" but only from last "no" in cell.

In this case result will be 5 for row 1, 8 for row 2 and 0 for row 3.

So this formula should automatically find last "no" in row and from that "no" count just "x's".


Thank you!
