I put in class wikis under parent page when doing the +options and parent but it's now showing up in the class wikis section.
You performed the parent page operation correctly. What the parent page does is create the links in the top left of your page that lets users navigate between pages. For instance, if you made the parent of inverse kinematics: forward kinematics and then the parent of forward kinematics: class wikis you would have something that looked like:
Class Wikis»Forward Kinematics»Inverse Kinematics
and both class wikis and forward kinematics would be links to those pages letting users navigate more easily.
In order to have your page show up on the Class Wikis page, which I took care of for you by the way, you need to edit the Class Wikis page and at the bottom of the page, underneath the previous link (seperated by a return for consistancy), you would add the following:
[[Your Page's Name Here | What You Want the Link to Say]]
Hope that clears everything up for you.
