Hai Bill,

Remco already pointed out how to fix your code, so I wil only add some noice:)
Maybe you are not aware of the fact that in python dictionary keys could wel
be tuples? Quite likely that someday you will be bitten by non uniquely conca-
tenatable account codes like 00,1 and 0,01:)

as bit-prevention you could change the key you use from

    dictionaryKey = (histRcd[0], histRcd[1], histRcd[2], histRcd[3])
