Good morning. I'm looking for a way to sum up the same amount field of the same customer, but for a different record.
the situation is:
<< id_cliente >>
<< Month >>
<< sign up >>
<< amount >>
there are more records with these items, but the first two are always the same.
Like the top? I can not use a portal because it would be nested ... so I had to solve it differently ... but now I have this problem.
