Errors In Function Code

Hi,

I'm pretty new to SQL and I'm having trouble with a function, probably just syntax. I'm trying to consolidate several rows of data into a single row text field.
The calling program can use views but not functions so I need to get a table into a view with the consolidated lines.

Also, I would think this could be consolidated to a single view that calls one function. Is that possible, how would I do it?

Thanks for any help,
Steve


VIEW WHERE DATA COMES FROM:
CUST_ORDER_ID | LINE_TEXT
number1 | first line item text
number1 | Second line item text
number1 | Third line item text
number2 | first line item text
number2 | Second line item text
...


VIEW I WANT:
CUST_ORDER_ID | CO_LINES_TEXT
number1 | Second line item text 'crlf' Third Line item text
number2 | Second line item text


FUNCTION CODE: This is the function code with errors

CREATE FUNCTION dbo.tvf_NC_CO_LINES_TEXT (@ORDER_ID VARCHAR(20))

RETURNS @NC_CO_LINES TABLE
(
CUST_ORDER_ID VARCHAR(20) PRIMARY KEY NOT NULL,
CO_LINES_TEXT VARCHAR(1000) NULL
)
AS
BEGIN
DECLARE @COLinesString VARCHAR(1000);
SET @ORDER_ID = CUST_ORDER_ID;
SELECT @COLinesString = COALESCE(@COLinesString + Char(13) + Char(10), '') + LINE_STRING
FROM NC_CO_LINES_STRING
WHERE NC_CO_LINES_STRING.CUST_ORDER_ID = @ORDER_ID
SET @COLinesString = CO_LINES_TEXT
RETURN
END;

GO
