Keeps saying missing ) after first argument


My code is below this. I follow a long with a guy on youtube and have it typed out exactly as he has and it still says "missing ) after first argument". First of all I have no idea what "argument" it is referring to since the only argument that is even close to happening is between me and my keyboard (aka the ■■■■ is an argument?). I am at a loss here I thought I was getting it but obviously not...

// Write your foodDemand function below.
// Last hint: In your reusable block of code, end each line
// with a semicolon (;)
var foodDemand = function (food) {
    console.log("I want to eat" + " " food);

foodDemand("Tacos de Gatos");


You will have to use a + sign to expand the string concatenation
console.log("I want to eat" + " " + food);
