Drop Down menu problem

Hey, guys.
I recently tried this amazing tutorial, but something got wrong.
In my trial forum everything was ok, but when I put it in my actual forum the arrows were gone and didn't work.

My forum: http://teenobsession.forumotion.com/
Version: phpbb2

I'll be very thankful if you can help me.

Where on your forum is this menu?

It's on the top, above the header.

You mean these:

Home
Tutorials
Resources
About Us
Advertise
Submit
Contact Us
More

Yes, exactly.

Please post the codes you are using.
