I have the following formula
=AVERAGE(OFFSET(BM51,-34,0,-12,1))

Next month, I will copy it one cell to the right and adjust the -34 to -35.
Is it possible through VBA to set the "-34" as a variable when it copies the
formula, and enter the new formula with something like "MyVariable -1". In
other words have it look to see what the current value is now, copy it to the
next cell and adjust the rows accordingly.
