Help with dropdown menu script !

Hi,

Well it’s a bit complicated I think, I’m now in charge of my company’s worldpress webpage since there is no one else.
I don’t know anything (only very basic concepts) about web page design.

I’m trying to use an already created dropdown menu but is giving me an error message (http://imgur.com/Tki7Xuz) whenever I press it. If I tab until I select the menu I can navigate straightforward with the arrow keys until I find the desired group where I want to post the content.
I’m using World Press 3.1 and the template was created by Paomedia.

Also I wanted to know if it’s possible to upgrade the current version (3.1) to the latest one without losing the template and the mapped content.

Thanks !

Regards,

Martin
