When it says no permission it’s talking about the user you’ve setup in your database doesn’t have permission to create the tables wordpress needs. If you’ve got phpmyadmin you can create the user and give appropriate permissions from there.
After you log into phpmyadmin click on privileges. Then click on edit user for the user you’ve created for wordpress. Then check the database specific privileges are set to all for the wordpress database.
Also make sure you check your wp-config.php file and set the database user name and password in that file.
If you have created the database in Plesk, and created the database user in Plesk, then the next thing you need to do is execute the WordPress installation process.
But based on your thread here, you must first get the WordPress files uploaded to your host first:

I talked to my host and I was told that I should use the httpdocs file as my root file, which I have done.
I’m not sure how much confidence I have in the answer from the host since he generally answers by telling me that they charge $250.00 for installing wordpress and subsequently trying to convince me that I am incapable of installing wordpress myselfdespite what the WordPress instructions say.
If I do not get a direct answer to my most resent question to the host server (pertaining to the memory setting for PHP), I will consider changing hosts to one of the hosts reccommended by WordPress. I have ecommerce files installed using a Storesense application installed on the host server. If one of the reccommended host servers is better for transferring ecommerce files, I would appreciate a reccomendation, especially if one of them also provides free installation of OS Commerce or one of the other Open Source ecommerce solutions.
