Javascript Gross & Net Pay Calculator

So I am making an elementary gross pay and net pay calculator in javascript/HTML. The webpage calculator takes the user inputted hours and rate, and spits out gross pay, and gross pay with tax. For some reason, it won't display the correct formula. Somewhere I made a grave error. If someone can steer me in the right direction that would be awesome.

Heres the code: 

<!DOCTYPE html>
<html>
<title>Gross + Net Pay</title>
<h1>Gross + Net Pay Calculator</h1>
<p id="demo"></p>
<p id="demo2"></p>
<script>
function myFunction() {
var rate = document.getElementById("payrate");
var hours =document.getElementById("hours");
var gross = hours * rate
var net = gross * .9 

 if (gross != null) {
    document.getElementById("demo").innerHTML = gross;
}
 if (net != null) {
    document.getElementById("demo2").innerHTML =net;
        }

  }
</script>
<body>
<form>
Pay Rate: <input type="text" id="payrate"><br>
Hours Worked: <input type="text" id="hours"><br>
<input type="submit" value="Calculate Gross + Net Pay" onclick="myFunction()">
</form>
</body>
</html>

Here is the corrected code. You had some typos, missing colons and you are also posting this via form. You don't need that unless you are handling this info in a different page.

<!DOCTYPE html>
<html>
<title>Gross + Net Pay</title>
<h1>Gross + Net Pay Calculator</h1>
<p id="demo"></p>
<p id="demo2"></p>
<script>
function myFunction() {
var rate = document.getElementById("payrate").value;
var hours =document.getElementById("hours").value;
var gross = hours * rate;
var net = gross * .9 ;

 if (gross != null) {
    document.getElementById("demo").innerHTML = gross;
}
 if (net != null) {
    document.getElementById("demo2").innerHTML =net;
        }

  }
</script>
<body>

Pay Rate: <input type="text" id="payrate"><br>
Hours Worked: <input type="text" id="hours"><br>
<input type="submit" value="Calculate Gross + Net Pay" onclick="myFunction()">
</body>
</html>
