I believe that you should be uploading files to public_html folder where it will automatically be duplicated to the www folder....also you probably don't want to park the domain if you are intending it to be viewed and live, as parked domain names are generally domains names that are registered with the InterNIC (and therefore reserved), but are not active for website or ecommerce service.
Parking domain names is useful if you have a domain name that you would like to reserve, but do not intend to use immediately. One of the advantages of parking domain names is that your domain is available when you are ready to use it. If you have a domain that you do not intend to use for a period of time, you may want to park it and save on monthly fees.
I think what you are looking to do is to add a sub domain. You can find detailed instructions on adding sub domains

You can access the entire cPanel User Manual
HERE and if you still are experiencing problems use their
LIVE SUPPORT I have always had any issues or questions answered immediately through their 24/7 live chat support.
Good luck with that and I hope that this info will prove to be useful for you
