Not a single item

I'm not sure why I keep getting "Not a single item" Item TDC_BOM = this.newItem("MIN_Delivered_Component","get"); TDC_BOM.setProperty("dpas","Remove"); TDC_BOM = TDC_BOM.apply(); List<string> TDCIds = new List<string>(); for (int v=0 ; v<TDC_BOM.getItemCount() ; v++){ Item dcBom = this.newItem("MIN_Delivered_BOM","delete"); dcBom.setAttribute("where","[MIN_Delivered_BOM].source_id = '"+TDC_BOM.getItemByIndex(v).getID()+"'"); dcBom.apply(); } return this.getInnovator().newResult("BOM items Deleted");
