I found no faults in your code that wouldn't allow you to change cards. But, in the "Next" button's code, try changing the last part of the timer to this:IF counter < 2 THENday = day + 1GOTOCARD 3END IFIt just might fix it. Though the fight scene will end 1 second early.
I strongly recommend tabbing conditions as well, as it makes code much easier to read. Also Gnome, when an IF THEN command only has 1 event under its condition, you can execute it in the same line like so:IF day = 1 THEN GOTOCARD whatever
