I go through each of the prompts, and when the last one is finished/closed, the whole page (and in some instances 'browser') freezes. I can't reload the page. Any idea why this might be?

JavaScript

<!DOCTYPE HTML>
<meta charset="UTF-8">
<html>
<head>
<script type="text/javascript" defer>
function delivery(){
var custName1 = prompt('What name will the order be under?');
var custAddress1 = prompt ('What address should we deliver the order to?');
var custNumber1 = prompt ('Please enter your phone number (land-line) in case we need to contact you');
while(custNumber1 > 8600000 || custNumber1 < 9999999);
	{var custNumber1 = prompt('Please enter a valid phone number. (8600000-9999999)');
}
if(custNumber1 <= 8600000 || custNumber1 >= 9999999);
	{alert('Is this information correct?\nCustomer Name: '+custName1+'\nCustomer Address: '+custAddress1+'/nCustomer (land-line) number: '+custNum1+'' );
}
}
</script>

I've tried debugging, I couldn't find anything...

I started this thread on a reddit post I made this morning. But in reddit, you can't exactly bump posts, so I moved it here.

Incorrect syntax, after the while and if statements, I put
';'. I thought that FireBug would pick up on the errors :o No matter.
