I am getting a variable not defined error for pie$\_1,$ although I have already defined it$.$ The error is on line $86.$ Here is my code.

def get$\_$pies$()$:

get$\_$pie$\_1()$

get$\_$pie$\_2()$

get$\_$pie$\_3()$

def get$\_$pie$\_1()$:

pie$\_1=$ str$($input$("$What is the first pie type that guests can choose from?: $"))$

return pie$\_1$

def get$\_$pie$\_2()$:

pie$\_2=$ str$($input$("$What is the second pie type that guests can choose from?: $"))$

return pie$\_2$

def get$\_$pie$\_3()$:

pie$\_3=$ str$($input$("$What is the last pie type that guests can choose from?: $"))$

return pie$\_3$

def check$\_$votes$($pie$\_$num$\_$votes$)$:

result $=$ True

if int$($pie$\_$num$\_$votes$)<=$ int$($guests$)$:

result $=$ True

else:

result $=$ False

return result

def update$\_$pie$($pie$\_$num$\_$votes, pie$\_$num$)$:

while check$\_$votes$($pie$\_$num$\_$votes$)==$ False:

print$("$The amount of votes for each pie may not exceed the total number of guests"$)$

pie$\_$num$\_$votes $=$ int$($input$("$How many people vote for $"+$ pie$\_$num $+"?$: $"))$

def get$\_$votes$()$:

print$("$There can only be one vote per person!"$)$

pie$\_1\_$votes $=$ int$($input$("$How many people vote for $"+$ str$($pie$\_1)+"?$: $"))$

update$\_$pie$($pie$\_1\_$votes, pie$\_1)$

pie$\_2\_$votes $=$ int$($input$("$How many people vote for $"+$ str$($pie$\_2)+"?$: $"))$

update$\_$pie$($pie$\_2\_$votes, pie$\_2)$

pie$\_3\_$votes $=$ int$($input$("$How many people vote for $"+$ str$($pie$\_3)+"?$: $"))$

update$\_$pie$($pie$\_3\_$votes, pie$\_3)$
