needing help with homework - calculator using javascript

i need to grab the text from the <input> and use that number in the equation.

<script>
function runMe(){
var x == document.getElementById('input1').value;
document.write(x);
}
</script>

<body>
<form>
Enter number <input type="text" id="input1" value="">
<input type="submit" onClick="runMe">
</form>

</body>

why doesnt it work????

You should be using one "=" to set a variable. Using double "==" is for comparison, like using in an IF statement to check if x == this.

var x = document.getElementById('input1').value;

Not really sure what you're doing with document.write(x); either.

in line 11 <input type="submit" onClick="runMe"> change to <input type="submit" onclick="runMe()" />
