Hi "officeplus215" ,

=SUM(H$8:H$19) would not work because inserting
rows will change the addresses. What you have to do is to
place the range within quotes so that it will not change:
=SUM(INDIRECT("H8:H18"))

I have a sheet that I use to track monthly sales. Each month I insert a
new row into row 7 and enter that month's sales. I have a formula in
row 4 =SUM(H7:H18) that totals the previous 12 months. When I insert
the new row, the formula changes to =SUM(H8:H19). Is there a way to
lock the formula so that it will always reference rows 7 to 18? I've
tried using a $ in front of the 7 & 18 but that doesn't work.
