Code:
          
                          usr.random = rand(1,20)
                                if(random == 5||random==1)
                                    usr.taiexp += rand(1,3)
                                    usr.taiup()
                                    usr.exp += rand(1,2)
                                    usr.Levelup()
                                    sleep(2)
                                    usr.canattack=1

Problem description:

error:random:undefined var

my question: Why it says: error:random:undefined var

It means that it has no idea what this thing you call 'random' is. You should probably define it as a var if you want to use it.
