What i intend to achieve with this is to have a list of distinct values on my drop down - see my code below; def __init__(self):         OBJECTID = []         for row in arcpy.SearchCursor("BldForm"):             OBJECTID.append(row.Combo)         self.items = sorted(OBJECTID)         self.editable = True         self.enabled = True         self.dropdownWidth = 'WWWWWWWWWWWW'         self.width = 'WWWWWWWWWWWW'        def onSelChange(self, selection):                 mxd = arcpy.mapping.MapDocument("Current")         for df in arcpy.mapping.ListDataFrames(mxd):             if df.name == "Layers":                 dfmain = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]         OBJECTID = []         for row in arcpy.SearchCursor("BldForm"):             OBJECTID.append(row.Combo) I'll kindly appreciate your help on this. ...
