need help understanding error message

I am not understanding what the following error message is saying:
An unhandled exception of type 'System.InvalidOperationException' occurred
in system.data.dll

Additional information: Inconvertable type mismatch between SourceColumn
'CUS_FNAME' of String and the DataColumn 'CUS_FNAME' of Byte[].

I am working with an access database, and the database has a field called
FNAME. In the data adapter, this same field is being used.

Charlie,

Can you show us some code, otherwise is in my opinion any answer hazard.

Cor
