Find first positive value in a column

[Guest]

I am trying to create a formula that will:
1. Search a column of numbers to find the first row with a positive number
2. Once found, I need to reference another column on the same row which
contains a date.
3. Finally, subtract that date from a fixed date (Jan 1, 2007) to end up
with a number.

I'm fairly new to Excel and wonder if this can be done with a formula or if
I need to get into VB script (hope not) .
Any help would be appreciated.

Try this array formula** :

A1 = 1/1/2007

B5:B20 = numbers
D520 = dates

=A1-INDEX(D520,MATCH(TRUE,A5:A20>0,0))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

You mean:
=A1-INDEX(D520,MATCH(TRUE,B5:B20>0,0))
(not A5:A20)
