I have a formula in cell C5 that displays the percent change between two
values in the same column. The formula reads =-(C10-C9)/C10. When I insert
a in row 8, the row numbers in the formula in cell C5 automatically increase
by one to reflect the new cells =-(C11-C10)/C11.

When I insert a row I want the formula to keep analizing the newly formed
cells, instead of automatically updating the formula so that the original
cells are used. Any help would be greatly appreciated
