This should be real simple... But it ain't... >.<

var x = document.getElementById('x');

function snooze()

{

x.style.height = '10px';

}

Upon execution, the error I get is:

TypeError: Result of expression 'x' [null] is not an object.

Edit: Heads up, it works when I put the var declaration inside the function. I don't understand... :-(

function snooze()

{

var x = document.getElementById('x');

x.style.height = '10px';

}
