Count the Number of Blank Cells, then Stop

[Guzzlr]

Hello All...
I have this:

=COUNTBLANK(Q4:AS4)

This will work, from the range of Q4:AS4, which is 29 blank cells. However, the numbers stop at BA4 so the COUNTBLANK function begins counting these blank cells.
What I need, is if the cells is blank (no number) in a row, it will count the number of blank cells, then stop at the first cell that has a number.
In the above example, the number would stop at 29 blank cells, because cell 30 in row 4 has a number >=0

Thanks for the help

So in this image, we see "0" in Range (V5:X5), so I would want a macro or formula to count the number of BlankCells from P5:U5, and then stop. Of course, each row to Last Row.
The problem with the formula COUNTBLANK, is it continues to count after X5

Thanks for the help
