Error with converting Celsius to Fahrenheit
<p>So I'm trying to create a script that converts celcius to fahrenheit.
When I run it I get an error on line 1.
Please help me out... I do not need a new code I just need this fixed :/</p>

<pre><code>window.addEventListener("load", init, false);

function init() {
    var celcius = document.getElementById("celcius");
    var fahrenheit = document.getElementById("fahrenheit");
    var button = document.getElementById("button");

    celcius.value = "";
    fahrenheit.value = "";
    button.addEventListener("click", controle, false);
}


function controle() {
    var celcius = document.getElementsById("celcius");
    var fahrenheit = document.getElementsById("fahrenheit");

    if ((celcius.value != "") &amp;&amp; fahrenheit.value != "") {
        document.getElementsById("note").innherHTML = "Please only enter information in one field."
    } else {
        calculate();
    }
}


function calculate() {
    var celcius = document.getElementsById("celcius");
    var fahrenheit = document.getElementsById("fahrenheit");
    if (celcius.value != "") {
        fahrenheit.value = (parseFloat(celcius.value) * 1.8) + 32;
    } else {
        celcius.value = (parseFloat(fahrenheit.value) - 32) / 1.8;
    }
    document.getElementsById("note").innerHTML = "Het omrekenen is fucking voltooid.";
}
</code></pre>
