# Excel/Excel complicated formula condition

Question
I am trying to created a summary result of other variables in my worksheet.
There are 5 variables (A, B, C, D, E) and 2 sheets (P1 and P2) that are in play.

Summary is listed vertically.

I can get this formula right.
=IF(P1!E9>0,P1!B9,IF(P1!E10>0,P1!B10,IF(P!!E11>0,P1!B11, IF(P1!E12>0,P1!B12,IF(P1!E13>0,P1!B13,"")))))
To give me A in the top cell. I than make the above formula shorter (Drop the first P1!E9 part) to get B in the next cell below and so on to get all the way to E.
Works great as long as there is always quantities in all variables (A-E) I get a vertical list of
A
B
C
D
E

But if A is not >0 I get
B
B
C
D
E
And if C is not >0 I get
B
B
D
D
E

How do I make it for the example of no A or C have the result of
B
D
E
only?

What I need is
1st Cell: Formula works
2nd cell: if 1st cell is blank or has B then do not show B
3rd cell: if 1st or 2nd cell is blank or has C then do not show C
4th cell: if 1st, 2nd or 3rd cell is blank or has D then do not show D
5th cell: if 1st, 2nd, 3rd or 4th cell is blank or has E then do not show E

I'm pretty sure this ARRAY formula will do what you want:

=INDEX(\$B\$9:\$B\$13, SMALL(IF(\$P\$9:\$P\$13>0, ROW(\$P\$9:\$P\$13)-8, ""), ROWS(\$A\$1:\$A1)))

Enter that formula into the first cell and confirm it by pressing CTRL-SHIFT-ENTER, and the "B" should appear if that's the first row with a value > 0.  You will know the array is active in that cell because you can see curly braces { } appear around your formula.

If you get a #VALUE error, you probably don't see the braces { } either, so try entering the formula again.  CTRL-SHIFT-ENTER feels weird until you're used to doing it instead of just ENTER.

Once the first value appears, copy that cell down.  You'll get #NUM errors when you run out of results.  You can suppress the NUM errors by adding an IFERROR() around the formula:

=IFERROR(INDEX(\$B\$9:\$B\$13, SMALL(IF(\$P\$9:\$P\$13>0, ROW(\$P\$9:\$P\$13)-8, ""), ROWS(\$A\$1:\$A1))), "")
