Data Link - GHV 2.2

Have a parallel Silverlight v2.2 viewer that brings in niche wall data via a data link, which works perfectly. Now that I'm attempting to establish a similar

viewer for GHV 2.2, the data link no longer works. Below is the statement that I'm using:

SELECT substring(composite_key, 1, 40) as SubComp_ID, level_1, site_number, site_status, interred_persons, rights_holders FROM GIS_StoneOrchard.dbo.GIS_Cemetery_Sites WHERE cemetery_id=@CemeteryID And level_1=@Level1 ORDER BY site_number -- LIKE 'N6%' 

After I select one of my niche walls, the Niche_Wall tab does not appear.

Any suggestions?
