I'm having trouble with the ULRazor template.

I downloaded and installed the ULRazor template and specified it in a skin.

1.  First, there was an error due to:  li@classString which I fixed by changing to li @classString

2.  Now, I am getting this compilation error:

Compilation Error

Source File: c:\inetpub\vhosts\test2.patapscoresearch.com\httpdocs\Portals\_default\Skins\AquaeHSC\menus\ULRazor\ULRazor.cshtml    Line: 2 

Can anyone help with this error?

Thanks in advance.
