If Formula

[Costill]

Can someone help educate me on the following formula:

=IF(INDIRECT(""&ROW()-2&"!$K$2")=0,"",INDIRECT(""&ROW()-2&"!$K$2"))

It is part of a purchase order log we use and the writer of the formula is
no longer with us.

It is looking in cell K2 of another worksheet, the name of that worksheet
being determined by the row number of the formula cell -2. So in H10, it
will look at K2 in sheet named 8, and if it is empty, return an empty cell,
else that value.
