Adding field values in a portal
Hi everyone, got a question for the addition of field values in a portal. I have 3 fields involved in this addition (Tot, Length, and Total). To begin with, Tot is not in a portal it's just a field outside the portal. I would like to add the value of Tot to the value of Length and store it in Total (Total = Tot + Length) which by the way are in the portal (Length and Total are in the portal). And then I would like to add the value of the Total of the first record with the value of my second value of Length (Total + Length) and save it again to the field Total. Problem is I can't get to make the second result correct.
Is there a way to do this?
