CMS Grid help?

[Budget101]

I'm trying to make a grid with the following:

3 Columns 310px 100% 180px

<div id="doc3" class="yui-tvb-r2">
    <div id="bd">
        <div id="yui-main">
            <div class="yui-b">
                <div class="yui-gc">
                    <div class="yui-u first yui-panel">
                        <ul class="list_no_decoration widget_list" id="widgetlist_column1">$column[1]</ul>
                    </div>
                    <div class="yui-u yui-panel">
                        <ul class="list_no_decoration widget_list" id="widgetlist_column2">$column[2]</ul>
                    </div>
                </div>
            </div>
        </div>
        <div class="yui-b yui-sidebar">
            <ul class="list_no_decoration widget_list" id="widgetlist_column3">$column[3]</ul>
        </div>
    </div>
</div>

But instead of the 310px code showing on the left hand side, it displays on the right. Anyone know how to fix that?
