You actually haven't given us very much to go on. No sample output. No indication of the table schema in the database. Inconsistent code (where does $CASHDB come from). Nothing we can run to reproduce your results (see I know what I mean. Why don't you? for hints).

I'd take a look at the column format for the field you are having trouble with. I'd guess it is limited to length 255.

Update: no indication that you have updated your node since the initial version of my reply.
