Custom Tool - not working.

I am having trouble getting a custom tool to work, I have an amateur level of VBA & C# knowledge .

I have tried many tutorials/guides.

I keep getting these unusable buttons that do not react other than being toggled.

The code isnt altered to any extent beyond what the guides suggest...

I'm just trying to get this template tool working before I can look into adding functionality.

Any help/suggestions would be much appreciated.

Thanks in advance.
