Hello,

I'm starting, a long with a mate of mine, a small blog/site on wordpress.
After selecting the theme I wanted to use, I came to the conclusion that I don't like the way the theme is ordered. However I'm completely new to coding and everything, so the task seems quite daunting. To see how it is now, see the site here: http://www.yuk-yuk.nl (don't mind the rest of the site, it's all about the way it's divided into two.

As you can see, there's a content part on the left, and two side bars on the right side of the screen (so content-sidebar-sidebar). What I want to get is that the structure sidebar-content-sidebar.

The thing is, the two side bars have seperate php-files with the coding, but get combined into one sidebar.php-file. This file is placed into one space in the CSS-sheet (See the codes below). Now, my roommate, who has some but not much experience with coding, thought I had to assign a new space on the left of the page for a second sidebar. This would have to be 'sidebar2.php' or whatever, and should get one of the sidebars assigned (again see the codes below). However, when I tried to do this, it didn't work out, unfortunately. I got an fatal error, saying that the funtion_get couldn't be found (used to collect the other sidebar-file). Unfortunately, I don't have screenshots of this, since I restored it last night.

My question is: How can I make sure that the site gets a sidebar-content-sidebar structure? What do I need to change in the CSS-file, and what do I need to make sure that second sidebar which I create gets assigned in the right way?

CSS-sheet, bolded where the sidebar is assigned:

sidebar.php file, where the codes of the two seperate sidebars get combined, when I tried to create a second sidebar, I asigned one of the two sidebars (lsidebar.php or rsidebar.php) to a similar file:
Code:
<div id="sidebar">
<?php include (TEMPLATEPATH . '/lsidebar.php'); ?>	
<?php include (TEMPLATEPATH . '/rsidebar.php'); ?>	
</div>
Code with which the sidebar gets integrated into other files. When I tried to create a second sidebar I tried to use the same code, with the ID of course changed to the appropriate file:
Code:
<?php get_sidebar(); ?>
If somebody could help that would be great, if more information is needed let me know. Bear in mind that I'm completely new to this, so that I might not know precisly what might be relevant and what you need to help me.

Thanks in advance.
