problems creating right and left sidebar in php output

[cassbiz]

Normally I would use tables,

In this instance I cannot

The PHP is populating data from the MySQL db and I can create either on or the other sidebars but both are not working at the same time.

My code is completely *$%*&#$ because I'm tired.

Does anyone have a simple set of sidebars that will work with id's and PHP where it doesn't float one on top of the other.

Here is my current css

                .containingbox
                {
                        width: 400px;
                        height: 400px;
                }
                .floatright
                {      
                        float: right;
                        clear: right;
                        width: 150px;
                        background-color: #90ee90;
                        margin: 0px;
                }

and then the php

        echo "<div align=right><a href=\"javascript:zimmer_link('";
        echo $zimmer;
        echo "')\" class=\"floatright\">Space $zimmer</a></div>\n";
