You can do something like this:

=SUM(IF(Barrett!$E$12:$E$574=IF($B$4="",Barrett!$E $12:$E$574,$B$4),.....

If you want to do that for all 3 variables then your formula will pretty
long.

Note that if all 3 variable cells are empty then the formula would return
563. So, you might want to add this to the very beginning of the formula
(making it even longer!!!):

=IF(COUNTA(B4:B6)=0,"",SUM(IF(Barrett!$E$12:$E$574 =IF($B$4="",Barrett!$E$12:$E$574,$B$4),.....

I'm helping my husband do a spreadsheet for work, and last time I had a
question I came here and I got much needed help but that was a while ago
and
now I'm back. <:O)

He works with lieterally hundreds of warehouses and the salesmen need to
be
able to see at a glance at what warehouse the product is in. Usually they
have a potential customer on the phone and need quick answers.

I have set up a page that referances ALL the warehouse pages. Each
warehouse
has their own page.......

This is what I have
=SUM(IF(Barrett!$E$12:$E$574=$B$4,IF(Barrett!$G$12 :$G$574=$B$5,IF(Barrett!$H$12:$H$574=$B$6,IF(Barre tt!$A$12:$A$574,1,0)))))
Whe
b4 = type of material
b5 = dimension of material
b6 = thickness of material
At first the salesmn were ok with it meeting ALL the criteria, it would
"pop
up" but in addition to that, they want to be able to do like a "quick
search"
and be able to just enter in 1 of the criteria instead of HAVING to put in
all 3....... They still want to utilize all 3 for when they need the
specifics, but say for example they need a certain type of material but
dimension and thickness doesn't matter... Right now they still need to put
that info in for it to pick up the warehouse. They want to be able to put
in
all 3 if they wanted or just 1..... Or say for instance they wanted 4x4
material but the other 2 criteria didn't matter........ How would I go
about
doing this??? I have NO IDEA how I would do this so any help you can give
will be greatly appreciated.
