Update And Delete Stored Procedures Not Working

I grouped everything together so you see it all. I'm not getting any errors but nothing is happening. I had this working and then I converted to Stored Procedures and now it's not.

CREATE PROCEDURE UpdateCartItem
(
@itemQuantity int,
@cartItemID varchar
)
AS
UPDATE CartItems Set pounds=@itemQuantity
WHERE cartItemID=@cartItemID
GO

<asp:Button CssClass="scEdit" ID="btnEdit" Runat="server" Text="Update" CommandName="Update"></asp:Button>

    Sub dlstShoppingCart_UpdateCommand(ByVal s As Object, ByVal e As DataListCommandEventArgs)
        Dim connStr As SqlConnection
        Dim cmdUpdateCartItem As SqlCommand
        Dim UpdateCartItem
        Dim strCartItemID As String
        Dim txtQuantity As TextBox
        strCartItemID = dlstShoppingCart.DataKeys(e.Item.ItemIndex)
        txtQuantity = e.Item.FindControl("txtQuantity")
        connStr = New SqlConnection(ConfigurationSettings.AppSettings("sqlCon.ConnectionString"))
        cmdUpdateCartItem = New SqlCommand(UpdateCartItem, connStr)
        cmdUpdateCartItem.CommandType = CommandType.StoredProcedure
        cmdUpdateCartItem.Parameters.Add("@cartItemID", strCartItemID)
        cmdUpdateCartItem.Parameters.Add("@itemQuantity", txtQuantity.Text)
        connStr.Open()
        cmdUpdateCartItem.ExecuteNonQuery()
        connStr.Close()
        dlstShoppingCart.EditItemIndex = -1
        BindDataList()
    End Sub

CREATE PROCEDURE DeleteCartItem
(
@orderID Float(8),
@itemID nVarChar(50)
)
AS
DELETE
FROM CartItems
WHERE orderID = @orderID AND itemID = @itemID
GO


<asp:Button CssClass="scEdit" ID="btnRemove" Runat="server" Text="Remove" CommandName="Delete"></asp:Button>

    Sub dlstShoppingCart_DeleteCommand(ByVal s As Object, ByVal e As DataListCommandEventArgs)
        Dim connStr As SqlConnection
        Dim cmdDeleteCartItem As SqlCommand
        Dim DeleteCartItem
        Dim strCartItemID
        strCartItemID = dlstShoppingCart.DataKeys(e.Item.ItemIndex)
        connStr = New SqlConnection(ConfigurationSettings.AppSettings("sqlCon.ConnectionString"))
        cmdDeleteCartItem = New SqlCommand(DeleteCartItem, connStr)
        cmdDeleteCartItem.CommandType = CommandType.StoredProcedure
        cmdDeleteCartItem.Parameters.Add("@cartItemID", strCartItemID)
        connStr.Open()
        cmdDeleteCartItem.ExecuteNonQuery()
        connStr.Close()
        dlstShoppingCart.EditItemIndex = -1
        BindDataList()
    End Sub
