???Help, D4 is not printing MemoFiels???

Hi there, does anybody knows if you have to do something special to
print memofields with D4 C/S, i'm using the Quickreport components. I'm
receiving the following error message "field XXX is of unknown type" if
i use the QRExpr component and if i use the QRDBText component no text
is printed.

Any help will be appreciated.

Thank in advance, Esteban.
