    Global variable

      How can I create a global variable? At the beggining it will be equal with 1. Each time I press a button it will grow by 1 unit.

          To make a global variable, just declare it. To make it start with a
          given value, declare it in a startMovie script.

          global gCounter

          on startMovie

          Then, to increment it every time a button is clicked, increase it by one:

          global gCounter

          on mouseUp me

          You must declare the variable as a global in every script that uses it.

            ok that worked, but I can't reset the value each time I start the movie... it keeps growing up

              Make sure that the startMovie handler I gave you is a #movie script (not
              a behaviour)- then it will reset every time you start it.

                What, exactly, is not working? When the projector starts (it does start), I see the initial screen that provides a choice of show to see. Upon selecting a show, spacebar should initiate the slide-show (images). What images are shown is listed in the text file. This does not happen. That is to say that the "action" (dissolve time. position, size) do occur, but there is no choice of images. Could the problem reside in the actual text file?
