INSERT EVENT TRIGGER

Hi All,

I am trying to INSERT INTO base table so that my trigger returns the expected output. But when I do that I get error-

Msg 8152, Level 16, State 13, Procedure tr_tblemployee_ForInsert, Line 10
String or binary data would be truncated.
The statement has been terminated.

I am using:

CREATE TRIGGER tr_tblemployee_ForInsert
on tblemployee
FOR INSERT
AS
BEGIN
    DECLARE @EmployeeID Int
    SELECT @EmployeeID = EmployeeID FROM INSERTED

INSERT INTO tblEmployAudit VALUES (
 'New Employee with ID =' +
   CAST(@EMPLOYEEID as NVARCHAR(20)) +
 'added at' +
   CAST(GETDATE() as NVARCHAR(20))
)
END

The tblemployee table has EmployeeID as INT type and the tblEmployAudit  table has EmployeeID as Primary key INT type.

Please advise.

Best R.
