I'm trying to only keep the first unique value of the GroupHeading field, blanking all others like it until I get to a different value. The code below is kicking out of the DO WHILE because the value of GroupHeading is changed by the REPLACE. I understand why, but how can I get around it?.

			SELECT WorkListXMLCursor
			SCAN
				m.GroupHeading = GroupHeading
				DO WHILE GroupHeading = m.GroupHeading
					SKIP
					REPLACE GroupHeading WITH ''
				ENDDO
			ENDSCAN
