If you are looking at how the numbers at the side appear, Its done through Javascript. Although this is a PHP forum, I'll explain how you can do this yourself via Javascript.

Each of the drop down menus are linked to a JavasScript function calculate() as you can see in the code you posted. This calls the function which is present in the maxheight.js file of which smantscheff has given the link. The relevent code is below.

function calculate(){ 
	if ( document.getElementById('q2').value != 0 ) { 
		var weekly = document.getElementById('q1').value* document.getElementById('q2').value* document.getElementById('q3').value; 
		var monthly = weekly*52/12; var yearly = monthly*12; 
		document.getElementById('weekly').innerHTML = parseInt(weekly); 
		document.getElementById('monthly').innerHTML = parseInt(monthly); 
		document.getElementById('yearly').innerHTML = parseInt(yearly); 
	} 
}

Javascript can be used to change values directly in any element of the DOM (Document Object Model) of HTML. In this case, they use the <span> element. For e.g. <span id="yearly">____</span> for the yearly data.

You can set the values in the HTML page by using the innerHTML attribute.

If you need further explanation of how this works please do let us know.
