      * Ligne: 63 Contexte : img.edhelgarthlogo  
        
        La propriété khtml-opacity n'existe pas. : 0.45
-----------------------------------------------------------------------
and my css command line is :

-----------------------------------------------------------------------
img.edhelgarthlogo {
position: absolute;
left: 50%;
margin-left: -490px;
z-index: 6;
filter:alpha(opacity=45);
moz-opacity:0.45;
khtml-opacity: 0.45;
opacity: 0.45;
}
-----------------------------------------------------------------------

nobody is able to help me nothing was found on internet by searching on
google and every website I saw said :

filter:alpha(opacity=45);
moz-opacity:0.45;
khtml-opacity: 0.45;

is ok. Whats the problem ?
