How you do this depends on what you mean by "copy", jeremiah. If you mean it
literally, you can't do it with worksheet functions; you'll have to do it
with VBA, and although it isn't hard, you'll have to switch this question to
the other forum, "Excel Programming".
On the other hand, if you're content just to display it in the new location,
you can use an IF function. If, for example, when you say "Col B" etc you
really mean "this cell in col B", you can put this function in each cell of
col D: IF(AND(A2=Sheet2!A2,B2="Year to Date"),Sheet2!B2,"").
But maybe you really mean the WHOLE column - that is, you want each cell in
Sheet1!D to display the same cell in Sheet2!B only if ALL of A:A equals
Sheet2!A:A and ALL of B:B equals "Year to Date". I can think of ways to do
that, but I'll bet they're unnecessarily complex; maybe someone else can
think of a simple way to do that.
