[SOLVED] Opacity issue between center column and right sidebar

Hi there,

I have opacity settings in place so the background shows through on both the sidebar and the center column, but no opacity between them. Where should I be looking to correct this, please?

This is one of the pages in question:

Opacity in the center is done this way:
ATA -> Style & edit center column:
filter: alpha(opacity=90);
opacity: 0.9;

and opacity in the right sidebar is handled with a div for the widget:
ATA -> Add HTML/CSS Inserts:
.frame {
background:rgb(255,255,255);
background: transparent\9;
background:rgba(255,255,255,0.9);
filterrogid:DXImageTransform.Microsoft.gradient( startColorstr=#e5ffffff,endColorstr=#e5ffffff);
zoom: 1;
}
.frame:nth-child(n) {
filter: none;
}

But I do need continuity between the two, and not what's there now (clear "bleed-through" of background.

Many Thanks for any help!! And yes, I will contribute to the coffers!
