Assume the variable is in cell A1

=SUM($B$5:INDEX($B$5:$B$1000,A1))

it's better to use index instead of offset or indirect since it is not
volatile

My variable is "# of weeks" and if I set it to "6", I want the formula to
sum
the values from cell B5 down 6 entries. Or if I set it to "5", I want it
to
sum the values from B5 down 5 entries....etc...
