If you mean that the *CONTENT* of the field is $aSomeGuyName$fAdress, then I would say the conversion program, converting from DBF to MySQL, messed up.
Somehow, it shoved two or more field values into a single field.
If the pattern is *consistent* for all records with that particular field, then we could probably figure out how to use MySQL to clean up the data. If it is not consistent, if it only happens in some records and not in others, then you'll probably need to use PHP to decode it.
If you could give some *REAL* examples, we might be able to help.
