>Hello all:
> I got good news. I found the cause for the problem: I have a variable I declared it as string(m.cs_id) and later on I assigned a numeric value to that vraiable. It does not give me an error but gave me an error when I browse the table because cs_id is one of the field in that table. Any ways, Thanks everybody for the time and the helps.
