field calculator error

I am novice in python and I am trying to run a function in the field calculator and I get this error. It drives me nuts. What is wrong?

Thank you.

Error:

error 000539: syntaxerror: invalid syntax (<expression>, line 1)

Pre-Logic Script Code:

def fnfindstation(addstation):

if addstation == "151" or addstation == "551":

formataddress ="Oleander Station 1 - Shift B"

elif addstation == "152" or addstation == "552":

formataddress ="Oleander Station 2 - Shift B"

else:

formataddress = "Outside Station"

return formataddress

Station = fnfindstation=( !district!)

since you are calling a function on a field, there is no need for an equal sign, since you are not setting a variable in your expression.

instead of

fnfindstation=( !district!)

try

fnfindstation(!district!)

Huh... I knew it was something simple.. has to get used to Python since it is so different that other languages. Thank you.
