This is the error on my website. No error in Visual Studio, it compiles just fine. This happens when I run the website locally and click the button to show the zones in Chrome or any other browser. I am completely stumped by this and I am looking for any help?? Greatly appreciated.

```

This is the method I am calling which shows line 125:
