That's what i want but is there a way to keep original set of records in the table.
>>I need to sum a set of fields by an other field in a table and i'd like to know if my idea is good enough.
>>(It seemed to be a bit clumsy).
>>The table is like this
>>A B C
>>aa 1 1
>>bb 2
>>bb 3
>>bb 4 9
>>cc 5 5
>>dd 6
>>dd 7
>>dd 8 21
>>
>>So I should sum field "B" by field "A" in the filed "C". I would use 2 do while loops, one of them goes through the table and the other one would sum up the filed B if there are more than two identical ones in field "A". Does it seem ok?
