iFrame Transparency, Cannot get it to work properly. Options

[C.Lime.Jello.]

Will SOMEONE help me please???

If the code is:

<!-- begin code provided by createblog.com -->
<DIV align="center" valign="middle" style="BORDER-RIGHT: blue 1px solid;
BORDER-TOP: blue 1px solid; FILTER: alpha(opacity=100); OVERFLOW: auto;
BORDER-LEFT: blue 1px solid; WIDTH: 850px; BORDER-BOTTOM: blue 1px solid;
HEIGHT: 470px; BACKGROUND-COLOR:
clear">
<!-- end code provided by createblog.com -->

Then you would change:

FILTER: alpha(opacity=100)

Right? And when you change that it should turn semi-transparent, right?
SO, why doesn't it work properly?!
