declaration error

[sarahgeorgee]

problem/issue description : the value of num3 is not declared

why the issue need to be fixed: since num3 isn't declared, the output that needs to be displayed in the variable "sum" will not be displayed.

how to reproduce, incase of a bug: num1 and num2 are declared in the program, and num3 is not declared. and this is a simple error of declaration. therefore
CORRECT : NUM1+ NUM2
INCORRECT : NUM1 + NUM3

other notes/environment: this can also be avoided by replacing the value of num2 with num3. that helps see the problem in a different way also mitigating the problem.
