how can i be able to get both of these codes to work together:

<border="0" style="position: absolute; top:10px; left:10px"></a><style>
img { filter:;}
a img{ filter:;}
a:hover img{ filter:Alpha(Opacity=100, FinishOpacity=0, Style=2, StartX=20, StartY=40, FinishX=0, FinishY=0);}
</style>

and


<STYLE type="text/css">A:hover{background:url(http://www.mypimpspace.com/graphic/albums/userpics/10001/sparkles.gif);}hr{background-image:url(http://www.mypimpspace.com/graphic/albums/userpics/10001/sparkles.gif); </STYLE><br /><a href="http://www.mypimpspace.com/" target="_blank"><img src="http://www.mypimpspace.com/images/button.gif" style="position:absolute; left:0px; top: 0px; z-index:9;" border="0"></a>

Everytime i put both of them the sparkle one always shows up and the circular transparency one doesn't. I saw one page where they both showed. How can i get them both to work?
