You don't upload, just type what formulas in which cells aren't calculating,
give us some sample data here to work with...
For example:

Say you have the Grade in cell B25, you type in 97, so in cell C25, you
would want the letter grade to show, i.e.:
C25: =IF(B2592,"A",IF(B2584,"B",IF(B2576,"C",IF(B25 68,"D","F"))))

Without knowing what formulas are in cells that aren't updating, and without
knowing what data you are entering that should update these formulas, no help
can be rendered.
