I have several rows which all start out as blank cells but then over time
start to have numbers (though the numbers start to come at different times).
I would like to write a formula that pulls the first non-blank cell for each
row. The numbers (once they start) are not sequential so i cannot use a
min/max function. There are also sporadic blanks which poses another hurdle.

For example:

A B C D E
Row
1. 15 11 23
2. 21 12 17
3. 2 4 78 65 13
4. 18 12

The formula i would like to write would result in the following:
1. 15
2. 21
3. 2
4. 18

I would assume there is a function that says "Return me the number in the
first cell in this row that is greater than 0"...I just cannot figure it out.
Please advise.

THANKS!!!
