Invalid column name in #temp table

I've got a query that dumps data to a temp table, then uses a WHILE loop to update a field in that temp table.  When I execute the SQL in Query Analyzer everything runs just fine, but when I call the stored procedure I get "Invalid column name 'notificationGroupName'" pointing to the initial insert into the temp table.  I also get another of the same error pointing to my ORDER BY clause when I'm finally selecting all the data in the end.  Can anyone point me in the right direction?

Thanks!

ALTER PROCEDURE [dbo].[sproc_dashboard_select_notifications]
	
	@UserID int

SET NOCOUNT ON;

CREATE TABLE #TempNotifications
(
	ID int IDENTITY,
	notificationID int,
	notificationDate datetime,
	notificationGroupName varchar(250),
	processStepID int,
	coID varchar(50),
	suiteID int,
	leaseID int,
	assetID int,
	woID int,
	notificationRelatesTo varchar(250)
)

--	Save all applicable notifications to a temp table
INSERT INTO #TempNotifications (notificationID, notificationDate, notificationGroupName, processStepID, coID, suiteID, leaseID, assetID, woID)
	SELECT notificationID, notificationDate, notificationGroupName, processStepID, coID, suiteID, leaseID, assetID, woID
	FROM tblNotifications
	JOIN tblNotificationGroupLevel ON tblNotifications.notificationGroupLevelID = tblNotificationGroupLevel.notificationGroupLevelID
	JOIN tblNotificationGroup ON tblNotificationGroupLevel.notificationGroupID = tblNotificationGroup.notificationGroupID
	WHERE tblNotifications.userID = @UserID AND notificationStatus = 0

SELECT *
FROM #TempNotifications
ORDER BY notificationDate ASC, notificationGroupName ASC
