Im confused? with this script says error Expected 'end' (to close 'then' at line 35), got <eof>

EOF stands for End of File. Each scope that gets created is required to be closed, in other languages it can be determined by different syntax, however Lua defines a closed scope via the end keyword.

At line 43 you didn’t close the scope respectfully, also left an open end in an improper scope too, at 71.

Fixed program.
