IE6 Png fix and fades causes Javascript Error

(parseFloat( elem.filter.match(/opacity=([^{)]*)/) [1] ) / 100).toString().}

Throws an error since on png fixed elements elem.filter.match may be null.

Can be fixed with :

(parseFloat( (elem.filter.match(/opacity=([^)]*)/)

[0,100]) [1] ) / 100).toString() :
