Hi Vellon,

I can't be 100% from your explanation but you need to call functions, they don't run automatically.

Please can you share the code you're having issues with.

how do i call a function or even a variable. here is my code if (day < 7) { greeting = "happy week"; }

The code you've supplied is a conditional (if statement) and inside that you have a statement which sets the variable greeting to a string with the value "happy week".

Let's say you're using that code to set an alert. You might do something like this.

var greeting = "Hello there!"; // Here I have defined the variable greeting to say "Hello there"
var isWeekend = true; // I have defined a variable that lets us know if it is the weekend and I have set it to true
if ( isWeekend === true ) {  // Now I have used an if statement to change the greeting if it is the weekend.
    greeting = "Hello there! It's the weekend!!!";
}
alert(greeting); // Now I have created an alert that will display the value of the variable greeting.

Only when I use the alert() method does anything happen.

Hopefully that helps :)
