G'day Brent,

It might not matter, but you have double %% in the DATA statement you have passed, 

and for whatever reason - I recevied advice from this list or OpenLayers list - I have all my variable names capitalised in the query:

					WHERE transferdate >= '%STARTDATE%' AND transferdate <= '%ENDDATE%'
						AND line_geom IS NOT NULL
						AND sourceshire NOT LIKE destinationshire
						AND sourceshire LIKE '%SOURCESHIRE%'

So I hope these might help if Steve's solution didn't
