need to change stored proc. a bit

ok here's the thing :

CREATE PROCEDURE Split
(
@OrderList varchar(500)
)

AS
BEGIN
DECLARE @OrderID varchar(10),@Pos int

SET @OrderList = LTRIM(RTRIM(@OrderList))+ ','
SET @Pos = CHARINDEX(',', @OrderList, 1)


IF REPLACE(@OrderList, ',', '') <> ''
BEGIN
WHILE @Pos > 0
BEGIN
SET @OrderID = LTRIM(RTRIM(LEFT(@OrderList, @Pos - 1)))
IF @OrderID <> ''
BEGIN
INSERT INTO Testowa(ide)
VALUES
(
CAST
(@OrderID AS int )

) --Use Appropriate conversion
END
SET @OrderList = RIGHT(@OrderList, LEN(@OrderList) - @Pos)
SET @Pos = CHARINDEX(',', @OrderList, 1)

END
END
RETURN
END
GO

what it basically does is - it takes a string like '34,2,3,5'
and takes ',' as a separator to retrieve values that it should insert into a table 'Testowa'

what i'd like to have is :
take string like '1,32,4,5' and recognize that it should insert values like this :

table Testowa
-------------
id | num
------------
1 32
4 5


can someone rearrange this procedure for me so it'd do this?

thanks
