It works fine for me. I would point out that column 21 for me in that
formula is W, not AG.

Hi all,

I have a formula I am trying to put together and it just isn't working,
despite it's simplicity - and wondered if anyone could point out where I'm
going wrong...

In cell C20 are the letters MP.
In cell AG20 (the 21st column in the vlookup below), is the figure 3.
In cell AT20, is the figure 37.

In cell Summary!$Z$7 is the number 17.

In cell D10 is the following formula:

=IF(OR(AT20=0,VLOOKUP($C20,$C$4:$AP$108,Summary!$Z $7+4,FALSE)=0),"",IF(VLOOK
UP($C20,$C$4:$AP$108,Summary!$Z$7+4,FALSE)AT20,"A LARM",""))

The lookup identifies the MP, finds the 21st column in the lookup, which
seems to be the figure 3, and compares it to AT20, which is 37. If AT20 is
smaller than the 21st column figure (3 in this case), "ALARM" is
displayed.
However 37 is clearly not smaller than 3. And the formatting is correct.

Anyone see why the formula results in "ALARM"???

Thanks in anticipation

Danny
