Try this on for size:
~ highlight the formulas you want to move
~ do a search and replace: search for the = sign and replace with your
initials. This converts the formulas from a dynamic Excel math thing
into a static text string, and Excel will not shift the formula
references
~ copy the range
~ paste into the new location
~ search and replace again: search for your initials, replace with the
= sign
~ take a $20 out of petty cash, and treat yourself to lunch
