How to find the first nonzero value in an array?

I need to be able to reliably calculate the first nonzero value in an array, then pull header info related to it.  I've figured out a way to do this, but it doesn't work all the time (7 of 33 lines return the array end location even though there are nonzero values earlier in the array).  Help?

To find the first nonzero value, I'm using MATCH(0,{cells},1).  No, my values aren't in ascending order but they do all start with zeroes, have a group of nonzero values, then maybe return to zeroes at the end -- the lines that work return the location of the last (left-to-right on the row) zero value before nonzero values begin.  I'm then using INDEX to pull the header I need from one column to the right of the returned MATCH location.  When it works, it's great -- when it doesn't work, it returns the final position in the array, which causes a #REF! error after I add one to the column...

I'm just confused why it works some times, and not others.  The cases where it doesn't work seem to be the smaller nonzero values, but increasing all values by 1000 didn't change the outcome.  The other possible thought is shorter nonzero value strings (one or two values, rather than three or four).

Here's a working line:  INDEX({"","","FY11","FY12","FY13","FY14","FY15","FY16","FY17","FY18","FY19","FY20"},1,MATCH(0,{0,0,0,0.35,0.45,0.45,0.45,0.45,0.45,0,0,0},1)+1)

Here's a nonworking line:  INDEX({"","","FY11","FY12","FY13","FY14","FY15","FY16","FY17","FY18","FY19","FY20"},1,MATCH(0,{0,0,0,0.025,0,0,0,0,0,0,0,0},1)+1)

Anybody have a better approach? Thanks in advance!
