EDIT: What is your expectation that the script should do? currently it stays AFK until it has to light up the incense (or if the timer ran out which you set in gui), isn't that what is happening? for example, if you enter and the incense isn't lit, it should by automatically light it for the first time then it starts a timer until the number of seconds(that is randomly generated between the range you selected in GUI) is reached, it will relight it and continues
