Spry Effects Error, Invalid Argument

[7079]

Hi,

I posted the page that i'm having trouble with online at:

http://7079.net/Spry/index.cfm

If you "click me", the page fades out and a div grows in the middle of the green area. The yellow box has a link to close it, if you click that, it will set the page back to normal. If you go and "click me" again, it doesn't work the second time, instead it gives an error on line 1240 which is this piece of code:

if (this.options.scaleContent)
{

for(var i=0; i < this.childImages.length; i++)
{
this.childImages[i][0].style.width = propFactor * this.childImages[i][1] + this.units;
this.childImages[i][0].style.height = propFactor * this.childImages[i][2] + this.units;
}
this.element.style.fontSize = fontSize + 'em';
}

if(this.enforceVisible)
{
Spry.Effect.enforceVisible(this.element);
this.enforceVisible = false;
}

I am having trouble figuring it out, i would appreciate any help you can offer.

Thanks,
