Help with Curriculum Menu

[beeswax]

I appreciate that I'm becoming a pain in the backside, but I'm really trying to get my head round this. I've created an addition to the Curriculum Menu (CEPA - Creative, Expressive & Peforming Arts) which appears in said menu. When you click the CEPA link either in the top menu or the curriculum menu, then the curriculum menu disappears/is not there. The CEPA article is still displayed. How do I fix this. More pertinently still does someone know of an online resource (I've tried the Joomla site but didn't come up with anything for this situation) which will help me and decrease the petsering on here?

Finally, how do I access the Greybox Gallery?
