My folder isn't working. Can someone help?

I have it set up like this: [[folder:Squishy Makeovers]]. I have folder control, and that works, but for some reason this isn't. Do you guys know how to fix this problem?

It would help if you gave more context. To work, a folder tag must be closed.

[[folder:My Folder]]

Stuff

[[/folder]]

It also must be unique. If you have more than one folder on the same page with the same title, they may not work as intended. (I'm not sure if that bug has been fixed or not).
