animation on open modal problem (moves top and hides itself)

[gerpaick]

Hi,
I have this situation:
on first modal i put some info and option to choose. then when i choose some option (using button click) first modal should close, and second shoud open to get more info.
but second modal opens correctly on center of the page, but after a very short moment it moves up and up, and i see only a small part of this modal.

i tried to do this in 2 ways:

$('#btnSystem1200cWybierz').click(function() {
    $('#krok2').reveal({
        onOpening: function(){
            $('#krok1').trigger('reveal:close');
        }
    });
});

and 2)

$('#btnSystem1200cWybierz').click(function() {
    $('#krok1').trigger('reveal:close');
    $('#krok2').reveal();
});

in both cases i have the same problem.
any idea what i am doing wrong?

to see this in action go to: http://alfen.linuxpl.info/test/ and click 'wybierz' button on 'System 1200 Classic' or 'System 1200 Classic Podmurówka' panel.

thanks in advance!

You might have had multiple instances of

<script src="...reveal.js"></script>

in your page. Similar problem, where "the modal appears in the middle, than runs away"
occured to me. Checking the page i've seen reveal.js being included multiple times. Leaving
only one solved it for me.
