The exact formulas depend on what you presently have in those cells (empty,
formulas, formulas returning 0 or ""), so start with something like this,
and post back with any problems:

Select E22 to E25, then,
<Format> <Conditional Formatting>,
And change "Cell Value Is" to
"Formula Is"
And enter this formula:

=SUM($E$22:$E$25)=$D$22

Click on "Format" and set your font to a nice Green,
Then <OK>

Then, click on "Add" for your 2nd condition,
And again change "Cell Value Is" to
"Formula Is"
And enter this formula:

=SUM($E$22:$E$25)<>$D$22

Click on "Format" and set your font to a nice Red,
Then <OK> <OK>,
And you should be done!
