How do I Create Rounds For Rock, Paper Scissors Game?

I've been working on a Rock, Paper Scissors project for python and pyqt6 practice. It's almost done but the problem I have is that I'm trying to implement a three round system. It's not working and when I open the the game menu, it starts at 3 instead of at 1 and work its way up to 3. There's also a picture I've provided where no button has been clicked. Pressing the buttons do not add to it either.

        self.startBttn.clicked.connect(self.start_clicked)

    #Changes screen after start button is clicked
