I'm trying to play a game on iWin games .com and got this error:Line 1484
Char 1
error 'false' is undefined
URL:>Link removed<
pos=left;iwin=ad;tile=1;dcopt=ist;sz=728x90;ord=56 21702929?
I am using Mozilla Firefox

I need a help to know what to do and how I can play the game.

You may wish to edit your question's subject. Either you are using Internet Explorer or you are using Firefox.

Regarding the error, if you trust the site, I would recommend trying various browsers to see if the game works then. You may find that the developer/s of the game only test/ed on specific browser/s. Trying different versions of the same browsers could be beneficial, too.

Also, if you find it works on no browser (say, MS Internet Explorer, Mozilla Firefox, Opera, Safari, etc.) or any of the versions you try, it might be the script is actually broken - consider contacting the developer or the site directly.

While this may sound like a lot of work, it of course depends on how much you want to play this game. :) And FYI, if you want someone to help debugging an online script/game/whatever, you may want to provide the URL next time.
