I am trying to get a message when you click "click me" button that says "yourname, you say you are "age" but I bet you are really "age + 10"

Also, when the number entered for age is 20 or greater the div id=noShow would show on website but if age is less than 20 just the message would display.

Trying to add into script and html but dont know how to get when you enter an age of 30 or greater into age input box, it will show the div id=noShow about trails and when an

age of less than 30 is entered, just the message will show.

I am having issues mainly with script and assume some in html5.

code is at bottom incase pictures are not good quality

	var $ = function (id) {
	return document.getElementById(id);
	}
	var displayMessage = function ()
	{
	var myFirstName = $("firstname").value;
	var myAge = $("age").value;
	var myTrueAge = myAge + 10;
	var myText = "Well " + myFirstName + " you say you are "
	+ myAge + " but I bet you are really " + myTrueAge
	$("mymsg").innerHTML = myText;
	}
	if (myAge
	document.getElementById("noShow").innerHTML;
	}
	window.onload = function ()
	{
	$("mybutton").onclick = displayMessage;
	}
