Formula Numeric field not calculating correctly

Hello all,
I have what's sure to be a simple oversight on my part.
I've likely been staring at this to long.
In the following formula, the 1st 3 cases calculate correctly, but the last one does not.
I know the why, but can't seem to figure out the fix.
I have tried putting the closing ) in several places before and after the last /100 but can't seem to close off the Sum() function in the last case statement.

Apologies for the inconvenience on this simple fix.
Here is the formula.
