Problem with User Defined Function

I wrote a UDF to get a rolling average based upon a date passed to the UDF. The error I get is:

Server: Msg 102, Level 15, State 1, Procedure fn_RollAverage, Line 26
Incorrect syntax near ')'.

The " AS " keyword is not valid in the @.TBLRESULT table declaration.
