I'm using Access as my database, and i have a table like this;
Schedule Inseam Size Total
----------------------------------------------------------
12100 30 32 10
12100 30 32 9
13100 32 38 7
14100 34 38 8
And i wan my table do the calculation like this;
Schedule Inseam Size Total
----------------------------------------------------------
12100 30 32 19
13100 32 38 7
14100 34 38 8
Means that if its have same "Inseam" and Same "Size" it will auto calculate for me. Any idea and advise on how to do this calculation? Thanks
