When i first created a spread sheet to make calculations. It would
automatically update as i added or deleted values. However, the document has
been saved and has not been used in a while. I have to go to each of the
cells, go to the formula bar, move the cursor after the formula and press
enter just to get the cell to update. I don't know what the problem is. It is
too time consuming to go to each cell just to have it recognize the new
values.

Any suggestions? Thanks!
