Hi Shotthebreeze.
You are trying to make the tutorial 'Show Different Navigation Menu to your Members and Non-members' works on your site?
I believe this would somehow similar to drupal, which i have experience on.
I am interested to try to fix your problem. Is it hosted in internet? or its local? If its local i guess it's more difficult for me to help you as I need to carefully study the errors, and refer to existing chunk of code.
If this is a hosted site, You may consider assign it to me and if i'm not able to fix, you don't have to pay me.
Hope to hear from you soon.
Regards
JY
