It's been a really long time since I tried to do forms in Javascript. I had a couple of books and finally found an example online that somewhat did what I was looking to do. What the form is supposed to do is allow the user to check various components for their computer and when they hit "calculate" it is supposed to display a price. Unfortunately, nothing happens when I hit "calculate." Can someone please tell me why this is happening because I can't seem to find the problem. Any help is appreciated! Thanks!

Hi. I would remove onsubmit="count()" from the submit button, and add onsubmit="count();return false" to the form tag so it's like this:
CODE
<form name="calc" method="POST" action="" onsubmit="count();return false">

The return false means we don't want to submit the form to a PHP script.

Now if we go to the count function in calculate.js and change it to something like this:
CODE
function count(){
document.calc.pay.value=666.66;
}

we see that it works (at least at saying everything costs $666.66). So that proves there must be something wrong in the function. Unfortunately in this case when we get it wrong, we may be sent to a blank page, but otherwise it's just the simple but tedious matter of debugging and continuing to add functionality.

You'd probably figure out you need to remove the space from:
var wireless price = 0;
so it's
var wirelessprice = 0;

Also, there is no ram756mb checkbox. Do you mean 768?

There is no novidprice checkbox. Do you mean novid?

There is no ddr5mb. Do you mean ddr5vid?

There is no noffice. Do you mean nooffice?

Also, although it works I'd suggest you only use var when declaring a variable, not upon every use.

I was somewhat bored, so here's what I have for a working count function at this point, but you'll need to work on it more as I notice some of the video cards are not being counted.

CODE
function count()
{

//Type variables
var pcprice = 0;
var laptopprice = 20;
var typeprice = 0;

//Processor variables
var singleprice = 1.67;

var htprice = 0;
var processorprice = 0;

var ram756mbprice = 22;
var ram1000mbprice = 30;
var ram1500mbprice = 45;
var ram2000mbprice = 60;
var ram2500mbprice = 75;

var ram3500mbprice = 95;
var ram4000mbprice = 110;
var ramprice = 0;
