guannstar buddie your code is perfect. i just want to tell you one think
# have you delete the function part of lvl 10 when your were making the code.
# construct2 take some time to update that thing.
# if the bug still persist then i have a quick solution . delete or uncomment on the lvl 10.
# now put againg the lvl 10 code do not copy form lvl 9.
# Export the project and close construct.
# now again import the project from exported folder. this should work.
