A few weeks ago I created a site with a left hand menu and everything is working fine. i am now wanting to add drop down menus to some of the main menus and though I can do this, I am getting error messages when I try to click through and i just can't work out why as the URL appears to be in the same format. I have just been copying the URL from the main heading and then changing the page name. For exmaple, this is the address for my main heading (Catalyst Infrastructure Funding).
This is the address for my drop down.
I am not very Sharepoint savvy!
