[thelist] Setting opacity with Javascript in IE7

[Mark Howells]

Can anyone suggest why this simple code doesn't work in IE7? (Yes,  
the element does exist.)

document.getElementById("id1").filter="alpha(opacity=75)";

  Setting the opacity sadly still has to be done with a filter and  
the equivalent CSS works fine.

#id1 {filter:alpha(opacity=75);}

Many thanks
