Hi there, Engr Faisal Ali! The problem here is capitalization. When learning to program, it's a good idea to assume that everything is case-sensitive. This is definitely true for variable names and function names, but can also be true for file and folder names.

You wrote:

var message= "Hello!"; 
console.log(Message);

But you meant to write:

var message= "Hello!";
console.log(message);  // note the lowercase "m"

Hope this helps! :sparkles:
