Hope this is in the correct forum, apologies if its not. 

I'm fairly new to jQuery and I've been asked to look at some code which has stopped working. The html / jquery code itself should work as follows. 

When someone clicks on a heading a table should display to the user, but unfortunately it doesnt. 

You can see the problem at the following link . Select people and then Mentors or members . Here is where the information should display to the user but unfortunately its not.

any pointers would be great.

Regards
