Hey everyone,

I'm trying to compare two columns, and use a threshold for what type of
differences are considered OK. I developed a forumla, but just realized
that it will not work for all instances. Here's my dilema.

........... Col A ............... Col B ............ Col C
Row 1 .. 5,000 ............... 3,000 ............ OK
Row 2 .. 3,000 ............... 5,000 ............ -2000

My current formula, to account for a 0.078 threshold difference is:
=IF(N8=O8,"OK",
IF(N8=(O8+0.078),"OK",
IF(N8=(O8-0.078),"OK",
IF(O8<=(N8+0.078),"OK",
IF(O8<=(N8-0.078),"OK",N8-O8)))))

I realized that this will only work for Data in Row 2. So in Row 2,
the values will fail all four IF statements, and the result will be
-2000 in Column C - this is correct. However, in Row 1, even though
the difference is larger than 0.078, the values pass for the 1st and
2nd IF statements, so they receive a value of "OK".

Is there a way to force the formula to have to pass all statements,
before assigning "OK"?

Is there a way where I can say, IF ((Difference between N1 and O1) =
0.078 or more, THEN (N1 - O1), "OK"))


Thanks for your help

Try

=IF(ABS(N1-O1)=0.078,N1-O1,"OK")

Whoops. Looks like you beat me to the punch. Thanks for your help.
That forumla did the trick.

You took the reverse approach, but both work just fine.

Hey guys,

Just wanted to let you know that I have it figured out. Someone over
at MrExcel helped me out.

Here's the answer:
=IF(ABS(N8-O8)<=0.078,"OK",N8-O8)


I didn't realize excel had the Absolute # formula in it.
