Sorting list items on the front end

Hello Sitefinitiers,

I read through probably all posts regarding custom sorting list items and none have provided a clear solution. So, I am adding yet another post in hopes that someone's able to help me.

Here's the list I need to sort:
desales.edu/.../meet-the-faculty

(You could see how not having our Faculty's name listed in alpha order is an issue, right?)

Attached, please find screenshots "CodeInVisualStudio" and "ErrorInWebBrowser."

I can see that the error in web browsers refers to lines 12-14 in the code, which needs code for the constructor.

I don't know what to put there. And, that's what I need help with, so far.

Can anyone help?

Thanks,
Gregory
