Having Trouble With My Script

[Johnex]

Hi all! I have made an animation script that makes a box move up or down if you hover over the respective button, it works fine on all browsers except firefox/mozilla which i find odd....

Could anyone check it out and see what i have done wrong? I will be very happy if anyone can help!

My script is here: http://johnex.se/dev/Javascript/Animation/animate.js
And here it is in action: http://johnex.se/dev/Javascript/Animation/

Thanks in advance guys!
