css not working on all computers

[ozpo1]

I wrote the following command in my html code:

<link rel="stylesheet" type="text/css" href="http://getcontractor.com/mystyle.css"/>

However, while in one computer the the browser reads the file as I wish it to, on a different computer it doesn't read the css file at all.
What can be the problem?

By the way, the browser on the second computer read other css files in other files. Thanks in advanced, Oz.

So what's different between the two? Browser? OS? Anti-virus?

try<link rel="stylesheet" type="text/css" href="http://getcontractor.com/mystyle.css" />or<link rel="stylesheet" type="text/css" href="/mystyle.css" />by the way, your regular expression should be/^[0-9]{5}$/
