Find the number of the lowest filled row

[Roberto Villa Real]

I'm building some complex sheets and to complete this task I need a formula
that finds "the number of the lowest row, of a column, witch is not empty".

For exemple, in Column A we have:

A1= 12.3
A2= 2.9
A3= 3.5
A4= (is empty)
A5= 3
A6= 10.3
A7= (is empty)
A8= (is empty)
Ax= (is empty)
.. .
.. .
(and so on)

Under A6, there is no filled cells in the column A.
I need a formula that returns "6", that is the number of the lowest row that
is not empty (A6=10.3).


PS:
I managed to get some good results adding formulas to a parallel column (B)
this way>

Column A Column B

A1=12.3 B1=If(A1>0;Row();0) (B1 returns 1)
A2=2.9 B2=If(A2>0;Row();0) (B2 returns 2)
A3=3.5 B3=If(A3>0;Row();0) (B3 returns 3)
A4= B4=If(A4>0;Row();0) (B4 returns 0)
A5=3 B5=If(A5>0;Row();0) (B5 returns 5)
A6=10.3 B6=If(A6>0;Row();0) (B6 returns 6)
A7= B7=If(A7>0;Row();0) (B7 returns 0)
A8= B8=If(A8>0;Row();0) (B8 returns 0)
.. .
.. .
.. .


And then the formula "Max(B:B)" returns the desired number (6).

But this way is not good enough because it needs a "parallel column" (column
B in my example) for EACH column I want to avaliate, and it would make my
sheet confusing for its users.

I need a solution so much... lol
Hope someone can help... lol

One way:

=MATCH(LOOKUP(99^99,A:A),A:A)

 

[T. Valko]

Don't really need LOOKUP:

=MATCH(1E100,A:A)

Yep ... but I did say "One way".<bg>
