"Uncaught SyntaxError: Identifier 'message' has already been declared"

const name = prompt("What is your name?");
const message = "Hello " + name;

console.log(message);

I'm following the video instructions, but for some reason is telling me that there is a SyntaxError. Please help.

Jessaly Sinchico the current code you have in your question is valid. The error is specific in the context that it means that you are trying to redeclare a const variable, which you can't do. Double check the video's code line for line. Notice how the teacher changes the keyword const to let to allow reassignment.
