Hello all.
Ok, I have a question about my formula in excel.

=if(b1<1,match(a1,a2:a$300,0),"ok")

b1 is a cell that I've used countif in. In this specific case, I'll either
have 1, or 2 as my values.

What I want to do is to locate the whereabouts of the second value that
matches a1, somewhere in column a.
This is why I started at the next cell down from my source cell--a1.
I.e., I am already aware of the first appearance of the number, I want
subsequent appearances, and locations.
The problem that I've gotten is that it's not showing the correct cell
location, and appears to be some 5 to 140 cells off from the actual location.
Here's my understanding of my question.

if the b1 cell's value does not equal 1, look throughout the chosen
range--a2 through a300-- for the specified cell--a1--value, if it's found,
tell me where it is; else if b1 does equal 1, everything is ok.

I.e., the matched value shows the location as 168, and is actually in 176 (I
used ctrl+f), another one states by match value that it's in 46, and by
ctrl+f, I found it in cell 157.
I'm not able to readily identify anything that I've done incorrectly here,
so a second, or nth pair of eyes would be appreciated.

As always, thank you, in advance.
