USPS Shipping Module Unwriteable

[dqc2010]

I'm hoping someone can help me. I'm new to Virtuemart and don't understand alot. I'm trying to get the USPS shipping module to work. I did successfully upload the newest version to my web server, but when I logged into Joomla/Virtuemart to try and configure the module, I'm got the following message: 'Error: File 'shipping/uspsv4.cfg.php' is not writeable. Ensure web server user has write priviledges to file'. Can someone please help me understand what exact steps I need to take to fix this?  Thank you!

You need to do that through a ftp client program such as FileZilla. Change the attributes of the file to 666.
