Counting occurences if between specific date range

I have an attendance tracker and I want to be able to select a date range and then have the sum available. The Data Validation worksheet shows the value each has, but i've included below for reference too. The table at the top does something similar, it counts a point if it is within the last six months and assigns a point based on the code. The worksheet "Aaron" is where I have comments/notes and such to help. The pivot table would be replaced with your formula. It is just for show.

So basically, I need the formula to look between the range of dates, and if an occurrence is listed, add them together. Since there are only three events with points, then i guess you could ignore the other letter codes.
