Average based on one group of values



     I have my basic three layer DB:




     I have the user enter the progress of the buildings construction (0 - 100%)

     I need to be able to get an average of all buildings progress within ONE project.

     so, if there are four buildings within one project, i need an average of the four buildings only. I am not sure how to write the average function which is Average ( field { ; field }). For some reason, when I try to use this with just the field name in the brackets, I only get the first buildings number, not the entire set.

     Why does it have (field { ; field})? why field twice? am I supposed to enter something for each "field"?
