Greetings Gurus,
I am trying to figure out how to link 2 tables in a 1 to many relationship, but show the sum of the many side.  
Here is an illustration;

Table1                       Table2        
   ColumnA                ColumnA     ColumnB
     group1                    group1        5
     group1                    group1        4
     groug1                    group1        1

output I am looking to produce
Table3
ColumnA    ColumnB
   Group1      10 ------>(5+4+1)
   Group1      10
   Group1      10
Let me know if this does not make sense.
