When I change scene I got this errors:

Runtime error F:\iOS\H&H\menu.lua:120: attempt to compare nil with number stack traceback: [C]: ? F:\iOS\H&H\menu.lua:120: in function <f:><br> ?: in function <?:214><br>Runtime error<br> F:\iOS\H&amp;H\menu.lua:120: attempt to compare nil with number<br>stack traceback:<br> [C]: ?<br> F:\iOS\H&amp;H\menu.lua:120: in function <f:><br> ?: in function <?:214><br>

I´m begginer… any help welcome ;).
