2 Column Layout (1 Widget Bar Expanded Content Area)

Hello, I have been trying to resolve an issue related to making the Sliding Door theme 2 columns. I have been somewhat successful and managed to remove the widget bar from the right hand side of the page but I have tried everything and can’t get the text to fill into the emptied area. I looked on the developer forums and followed the steps laid out in the posts by ‘molu’ ‘hijack’ and ‘rocksIT’ within this thread:

https://mac-host.com/support/viewtopic.php?f=9&t=7&sid=8ec573e98e6899c26a5286ca74341aa8

I’ve quadruple checked my style.css and sidebar.php files and even played around with the parameters with no success (the closest I’ve been was when I played around with the ‘overflow: hidden’ parameters and managed to get one of my youtube embeds to fill out the widget area, but not the text).

I also tried to register on the mac-host forums with 2 different email addresses but I never received an activation email response (despite trying to have them resent). Please help! It seems as if the forum is not accepting new members at this time or the system that sends out activation emails is not working.

Anyway, I have almost completed the entire process but I just can’t get the main content to expand into the space that has been vacated by the removal of the second widget column. The forum suggests that adding a value of ‘width: 630px’ under #content would resolve this problem but it has not been the case for me. Anyway I can provide screenshots of my style.css or sidebar.php if anyone has any ideas. Thanks.
