isAdmin and isStudent have already been declared as const on lines 1 and 2. Since those variables exist, you can't then declare more variables with the same name.

Should look like this.

const isAdmin = true; const isStudent = false; let message;

if (isAdmin == true) { message = "Welcome admin"; }

const isAdmin = true; const isStudent = false; if ( +isAdmin +=== true ) { message = "Welcome admin"; }

this is what i have now and it is asking if i am including the isAdmin variable inside the if condition

You don't want to use the plus symbols there, as that's only for numbers, not booleans. The code you typed in your original post is good if you just remove the 2 let variable lines for admin and student.
