Display dialog after choose from list - applescript

Question

I have been playing with applescript for a while and i am making a text version of pokemon. I have a choose from list and a if statement to start a display dialog. when you press Run it should say "You cannot run from a trainer battle" but the display dialog never opens. I can't see what is wrong. I have been searching google but can't find a solution
here is the code
set userStarter to "undefined"
set starterHP to "undefined"
set starterLV to 5
set starters to {"Charmander", "Bulbasor", "Squirtle", "Pikachu"}
set userName to "undefined"
on battle(traner)
display dialog traner & " wants to battle!" buttons {"Next"}
set battleMenu to {"Attack", "Bag", "Run"}
set temp to {choose from list battleMenu}
if temp is "Run" then
display dialog "You cannot run from a trainer battle" buttons {"Ok"}
end if
end battle
display dialog "Welcome to text based Pokemon!" buttons {"Play", "Quit"}
if the button returned of the result is "Play" then
set temp to display dialog "What is your name?" default answer "Ash" buttons {"Submit"}
set userName to text returned of temp
set userStarter to {choose from list starters}
display dialog "Oak: Okay " & userName & " here is your " & userStarter buttons {"Next"}
display dialog "Gary: Hey, lets battle!" buttons {"Battle"}
battle("Gary")
end if
here is the log
tell application "AppleScript Editor"
display dialog "Welcome to text based Pokemon!" buttons {"Play", "Quit"}
--> {button returned:"Play"}
display dialog "What is your name?" default answer "Ash" buttons {"Submit"}
--> {text returned:"Ash", button returned:"Submit"}
choose from list {"Charmander", "Bulbasor", "Squirtle", "Pikachu"}
--> {"Pikachu"}
display dialog "Oak: Okay Ash here is your Pikachu" buttons {"Next"}
--> {button returned:"Next"}
display dialog "Gary: Hey, lets battle!" buttons {"Battle"}
--> {button returned:"Battle"}
display dialog "Gary wants to battle!" buttons {"Next"}
--> {button returned:"Next"}
choose from list {"Attack", "Bag", "Run"}
--> {"Run"}
end tell

Okay, I found the problem.
This line is wrong, remove the { }: (otherwise you are pushing the return of the choose from list into a list, the return is already a list)
set temp to {choose from list battleMenu}
Then choose from lists returns a list so you have to check so:
if temp is {"Run"} then
display dialog "You cannot run from a trainer battle" buttons {"Ok"}
end if
(But if you want to show up the dialog if you press bag you should replace "Run" with "Bag")
The complete code is then:
set battleMenu to {"Attack", "Bag", "Run"}
set temp to choose from list battleMenu
if temp is {"Run"} then
display dialog "You cannot run from a trainer battle" buttons {"Ok"}
end if
