Overview

Create two error variables, one called ErrInvalidValue and the other called ErrAmountTooLarge. Provide the static message for each variable. Then write a function called checkAmount that accepts a float64 type value and returns an error value. Check the value for zero and if it is, return the ErrInvalidValue. Check the value for greater than $1,000 and if it is, return the ErrAmountTooLarge. Write a main function to call the checkAmount function and check the return error value. Display a proper message to the screen.
