Oracle pipelined table function table row type query

Hi all, 10.1EE on W2K. I am attempting to write a pipelined table function that returns a type typTest. I want typTest to be a row type of an existing table, not a new object definition, but I keep getting errors. Does anyone have any suggestions.

Thank you
Barry

CREATE OR REPLACE TYPE typTest AS TABLE OF test1%ROWTYPE; /
