Unexpected Symbol 'end-of-file' C# Error CS8025

Hello, I compiled the following script and I am very new to coding in C sharp. I do not know why I am getting this error "Unexpected Symbol 'end-of-file'". I check to see if I was missing a bracket or add in the next one and I cannot seem to fix it. I know somewhat about JavaScript but I have never compiled script in C sharp.

I have included the full script.

Thank you, Dan
