i tried searching couldent find answer, made account ask this

print("welcome text rpg \n"); function command()     print("what want do? \(\"help\" help\) \n note: must in caps")     input = io.read()     --condition = input == "help" or input == "east" or input == "west" or input =="north" or input == "south" or input == "shop"         if input == "help" or input == "east" or input == "west" or input =="north" or input== "south" or input == "shop"             --future game code         end end command() 

you need change:

function commmand() 

to

function command() 

note removed m.
