Hi Gena, there are two small issues with the code.

if (isAdmin = true) { // [1]
    prompt("Welcome Administrator") // [2]
};

Two weeks is a while, here's what you may have forgotten.

  1. Comparisons to see if two 'things' are equal are done using double equals (==). Assignment is done using a single equals (=), so you aren't actually comparing the value of isAdmin to true, you are assigning it the value of true.

  2. Prompts are used to gather inputs from the user. You want to use an alert here to display the message because you are simply telling them something.

You don't need the semicolon at the end of an if statement.

if (isAdmin == true) {
    alert("Welcome Administrator");
}
