Looking at rows 2:4888, I want to find the first row number "x" in which
OR(Hx<Kx,Ix<Kx,Jx<Kx) is true.

How can I write that formula in Excel 2003?

I tried the following array formula, to no avail:

=MIN(IF(OR(H2:H4888<K2:K4888,I2:I4888<K2:K4888,J 2:J4888<K2:K4888),ROW(G2:G4888)))

making sure that the condition is first true in row 4.

But that formula always returns 2.

I confirmed that the formula is an array formula enclosed in curly braces.

Also, I filled a parallel column with =OR(H2<K2,I2<K2,J2<K2) and copied
down to confirm that the OR function first returns TRUE in row 4.
