Right Hand Column Does Not Align Properly in IE6/7/8 - html

Question

I'm new to this but here goes. I have been developing this website http://www.panelmaster.co.uk and i have managed to solve the majority of design problems but one!
If you take a look at the site in IE the right column seems to drop down and is not aligned with the right and centre column. This problem only occurs in IE as upon testing i found it was fine in firefox and safari.
I have provided below the CSS for the website.
I would appreciate if you guys can help me with the problem.
Thanks in advance. :)

Answer 1

Try moving the DIV with the class "templatemo_sidebar_wrapper" inside the DIV with the class "templatemo_content_wrapper".
On another note, there is quite a bit wrong with your site. I'm not trying to frustrate you or put you down, but you really should invest a serious amount of time into learning web design. It took me about 1 minute and 45 seconds to load your site which has a footprint of almost 10MB. This is extremely unacceptable by any standard. I would highly recommend switching to www.squarespace.com or something similar. I can tell you right now that it would cost more money to have a web design company fix your site than it would to have them design one from the ground up.
In its current state, your website will likely hurt your business more than it will help. Good luck.
Edit: Move "templatemo_sidebar_wrapper float_r" inside "templatemo_content_wrapper" (I'm not sure this is going to work...you have a lot going on on this page). Your code currently looks like this:
<div id="templatemo_content_wrapper">
<div class="templatemo_sidebar_wrapper float_l"></div>
<div id="templatemo_content"></div>
<div id="content_bottom"></div>
</div>
<div class="templatemo_sidebar_wrapper float_r"></div>
