Need Help Entering the Correct Data on Site Setup Window

Question

[DW CS5 on a Mac OS 10.7.5]
I get an "FTP Error Message" after entering data on the Site Setup window after pressing Test.
I want to upload to my host/server's cPanel one of a number of subdirectories that I have on my root directory. My first attempt at uploading the first subdirectory failed. Can someone help me determine which of my Site Setup entries is incorrect and what the correct entry ought to be?
Perhaps I'm entering incorrect data in the "Root Directory" or Web URL" fields. My host server has given me the correct data, which I've carefully entered. Unfortunately, my testing on the Site Setup window continues to get this message: "An FTP error occurred — cannot open server folder /public_html/alaska/. Access denied. The file may not exist, or there could be a permission problem." Support staff at my host/server cannot determine why the uplaod attempts fail.
I'll appreciate your guidance. Thanks, very much.

Brett, thanks for your prompt e-reply.
Unfortunately, removing the entry from DW's Root Directory field enabled a successful test, however, it caused all uploaded files to wind up in my very large root directory.     ( :-(      I had to do a lot of file management and deletions to clean up the root directory.
My numerous approaches, after receiving your suggestion, appear to have found a successful workaround. Here's what worked:
-- While in cPanel's File Management window, I selected the "/public_html" folder in the left column and clicked "New Folder" from the top toolbar. Once the new subdirectory folder was created, I went directly to the DW app where I then clicked the icon (atop and to the far right of the Files panel) subtitled "Expand to show local and remote sites".
-- With DW's expanded window open, I selected the new folder name in the left half of the window. I then dragged and dropped all the files that were in the right-column's subdirectory's folder to the new folder in the left column.
-- After completing the drag and drop effort, I checked cPanel's File Management window and verified that all files went to the appropriate subdirectory folder.
-- Finally, I opened the site's pages online to see that all worked as intended.
Over all, I wish DW were more reliable, such that when testing setups for *subdirectories* that have "/public_html" in the "Root Directory" field, they will *all* test successfully.
Sadly, Adobe no longer supports CS5.    (  :-(
Nevertheless, thanks for your assistance, Brett.
