this is a sumarize function.
You will need to right click on the area field and hit summarize.
Then add the value field and sum it. After you complete that you can join that table back to the original data using the id field.

NOTE: it is advisable to not use the fid,OID field for your id. Just create a new field and calculate the value from fid into it.

using summarize doesnt group data by area, summarize calculate total of field –  Rasyid Ahyar Dalimunthe Jan 28 '13 at 16:13
    
Use the Summary Statistics tool in ArcToolobox to get at the summarize and grouping (case field) functionality. –  ccn Jan 28 '13 at 17:43

when he summarizes on "his" area field it will give a count of all the 1s, 2s, etc. adding the value and making it a sum, he will get 1,3,107. join that to the original data and he will get. 1,33, 107; etc. –  Brad Nesom Jan 28 '13 at 20:16
