Project Training Days

Working on poorly scoped variables that might cause en errors.

Project description;

As a seasoned athlete, one of your favorite activities is running marathons. You use a service called Training Days that sends you a message for the event you signed up for and the days you have left to train.

Since you also code, Training Days has asked you to help them solve a problem: The program currently uses the wrong scope for its variables. They know this can be troublesome as their service evolves. In this project you will make Training Days more maintainable and less error-prone by fixing variable scopes.

The errors are resolved and in comments there is process of making the change.

This project is inspiration from CodeAcademy, and will be updated and edited in the future
