Merge with field mapping

[CCWeedcontrol]

I  am trying to merge five layers into one with only three fields. The code merges the layers fine with out error but the output layer has all the layers fields and the RD_Owner field doesn't have the attributes merged. so i am guessing my fieldmapping isn't correct. I would appreciate any help.

HwyNpaPub = 'C:/Temp/HighwayDistricts.gdb/HWY1'
HwyNpaPr = 'C:/Temp/HighwayDistricts.gdb/HWY2'
HwyCan = 'C:/Temp/HighwayDistricts.gdb/HWY3'
HwyG = 'C:/Temp/HighwayDistricts.gdb/HWY4'
HwyNP = 'C:/Temp/HighwayDistricts.gdb/HWY5'

FieldMapString = '''

STREET "STREET" true true false 50 Text 0 0,First,#,{0},STREET,0,11;
ROAD_TYPE "ROAD_TYPE" true true false 70 Text 0 0,First,#,{0},ROAD_TYPE,0,11;
RD_Owner "RD_Owner" true true false 255 Text 0 0 ,Join,#, {0}, RD_Owner,-1,-1;

'''

def Layers1(HwyNpaPub,HwyNpaPr,HwyCan,HwyG,HNP1):
    fieldmappings = arcpy.FieldMappings()
    fieldmappings.loadFromString(FieldMapString)
    return fieldmappings

def main(args=None):
        if args is None:
                args = sys.argv


arcpy.Merge_management([HwyNpaPub, HwyNpaPr, HwyCan, HwyG, HwyNP], 'D:/GIS Folder/HighwayDistricts.gdb/TEST', Layers1(HwyNpaPub, HwyNpaPr, HwyCan, HwyG, HwyNP))‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

@StuartMoore, this is a very old thread. I suggest creating a new question with the code you're running and reference the post from @RandyBurton
