haven't had time to think through a solution, but i just wanted to respond
to Jerry's post about
I am not aware of any Excel function or combination of functions that can
test for "Any cell in Column AA=A1"
the countif function can be used for this
e.g.
=COUNTIF(AA:AA,A1)
will give you the number of times it is found and
=IF(COUNTIF(AA:AA,A1)=1,"found',"not found")
will give you whether or not it is found

hopefully will have time for a more detailed answer later on ...

You would have to either write a function in VBA or use helper cells to do
it.

I am not aware of any Excel function or combination of functions that can
test for "Any cell in Column AA=A1" If you are willing to restrict to a
subset of a column, then you could use an array formula like
IF(COUNT(FIND(A1,AA1:AA100)),"found","not found")
but you would quickly run out of nesting levels. Array formulas must be
array entered (Ctrl-Shift-Enter).

What type of formula would respond to the following conditions 12 (excel
seems to only permit up to 7...is it possible to get around that?):

IF Any Cell in Column AA= A1 and Any Cell in Column AB =B1 then C1=555
IF Any Cell in Column AA= A2 and Any Cell Column AB =B1 then C1=666
IF Any Cell in Column AA= A3 and Any Cell Column AB =B1 then C1=777

IF Any Cell in Column AA= A1 and Any Cell in Column AB =B2 then C1=888
IF Any Cell in Column AA= A2 and Any Cell in Column AB =B2 then C1=999
IF Any Cell in Column AA= A3 and Any Cell Column AB =B2 then C1=000

IF Any Cell in Column AA= A1 and Any Cell in Column AB =B3 then C1=111
IF Any Cell in Column AA= A2 and Any Cell in Column AB =B3 then C1=222
IF Any Cell in Column AA= A3 and Any Cell Column AB =B3 then C1=333


IF Any Cell in Column AA= A1 and Any Cell in Column AB =B4 then C1=1212
IF Any Cell in Column AA= A2 and Any Cell in Column AB =B4 then C1=2323
IF Any Cell in Column AA= A3 and Any Cell Column AB =B4 then C1=4545

help me please?
