syntax error, and call functions.

[Ayiden]

First thing is first this program is meant to convert feet into inches. my first problem was that past the intro, I forgot to call the rest of the functions, so I just want to check and see if how I have it set up to call the rest of the functions will work. 

def main():
    #variables
    feet = 0
    inches = 12
    feetInches = 0
    intro()

#intro
def intro():
    print ("This program will help you convert how ever many feet you have into inches")
    getfeet()

#main calculation
def getFeet(feet):
    feet = input("How many feet do you have?")
    print (feet)
    inchesCalculation()

def inchesCalculation(feet, inches, feetInches):
    feetInches = feet * inches
    display()

def display(feet,feetInches):
    print ("There are " feetInches "inches in " feet "feet")  #here at feetInches I am getting a syntax error and I don't understand why.

main()
