I've attached a sample - right click and save locally, right click, select design and preview. Add some rows to the repeating table, and set some of the fields to the same value. For your formula, I'd try: xdMath:Eval(xdMath:Eval(xdXDocument:GetDOM("Electrical_requisiton_Drawings")/dfs:myFields/dfs:dataFields/d:SharePointListItem_RW[not(d:Drawing_No = preceding-sibling::d:SharePointListItem_RW/d:Drawing_No], 'concat(d:Drawing_No, ";")'), "..")
