I am an admin trying to design the main page of a wiki. There was some code that I copy-pasted from another wiki, and modified to go well with the theme. I tried to add a comment to credit this other wiki, but it won't let me. I'm sure that this is the way to add a comment in the main page source code:  But for some reason, when I type it in, all the other code below the comment doesn't even show up. The comment doesn't even turn a different color like comments are supposed to.

Another really weird thing is that for some reason, even though I can group all the text on the left in "column left", it won't allow me to make a "column right". I have the code set up like this:  Wiki Main Page Text   Wiki Right Column Text  But for some reason, the text in the "column right" won't even show up. It's boggling my mind. What do I do about these issues?
