why is this not working?

'' javascript var html = ''; var red; var green; var blue; var rgbColor;

function randomColor { red = Math.floor(Math.random() * 256 ); green = Math.floor(Math.random() * 256 ); blue = Math.floor(Math.random() * 256 ); rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')'; html += '<div style="background-color:' + rgbColor + '"></div>'; }

for (var i = 0; i < 10; i +=1) { randomColor; } document.write(html); ''

For code formatting, use 3 accents, not 2 apostrophes.

``` :point_left: this

'' :point_left: not this

You should declare functions like this:

function myFunction () {
    some code here;
}

and to call it just do like this:

myFunction();

The pair of () is the correct syntax of functions if you forget to use it you will find errors.

Hi Matthew,

It's just a simple syntax error! You've just forgotten to add a pair of parentheses () in your function declaration and call.

Previewing the workspace in your browser and inspecting the console using your browser's dev tools yields the following error message:

Uncaught SyntaxError: Unexpected token {

...providing a hint that something is missing in the syntax of your function declaration.

Hope this helps!
