Hello, we have to create a football scoreboard in Visual Basic.
Purpose: The application calculates the points scored during a football game by one team
- The user clicks the enter score button in an input box object to enter a score after the football team scores
- Each score and running total are displayed in a list box
- After the user clicks the cancel button in the input box object to end the game scoring the total final score is displayed
- A file menu with a clear (clears scores and results) and exit (closes app)
- Non numeric values shall not be accepted
- Negative value should not be accepted
I am really struggling in this class so I used some example code for another project from the book. The first problem I'm having is when I go and run the program and type in the first number I get the negativenumber error. I'm also not sure if the program will actually run (again I am very lost in the class) If anyone could take a look and tell me where I am going wrong I would really appreciate it.

I don't know if this is right? Please check for me please and thank you!
