For some reason on my blog at http://ashleysguide.wordpress.com the right column somehow got moved to the bottom. I don't know if I messed up the coding somehow in one of my posts or what. How do I get it back to be on the right side?

Try making one of the column a little tinner.

I'd first off suggest going through your coding for the theme and makes sure all tags are closed and you didn't leave anything open.

Close all the tags correctly. Look for codes line by line. The code referring the sections may be open.
