Because variables act differently when used within functions. If you create a variable outside of a function, then that function will not be able to access variables outside of it and vice versa. In order to use a variable within a function that has been created outside of it you have two options:

- Either define the variable as global within the function

- Or pass that variable as a parameter to the function
