For this sort of logic I prefer to use just one scan.

>Replace the SCAN/ENDSCAN with another DO WHILE

>SELECT WorkListXMLCursor
>GO TOP
>DO WHILE !EOF()
>      GroupHeading = GroupHeading
>      DO WHILE GroupHeading = m.GroupHeading
>            SKIP
>            REPLACE GroupHeading WITH ""
>      ENDDO
>      SKIP
>ENDDO
>

>>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?.
