I am speaking about windows, xampp apache automatically takes port 80. You don't have to put in :80. I go with what the root is.
Mine is phptesting/
Also, make the testing server folder a solid name. I think I see a - in yours.
My phptesting folder is in c:/xampp/xamplite/htdocs/phptesting.
The other thing I saw was your admin as a name and root as the password. Once you have your MyphpAdmin working, follow that doc. link I sent you. If you don't have admin as a name, you are wasting your time. You can add users and set different parameters for each one.
That is the info you put for your connection. Make sure you bring that database in the php area. You have to import it.
Hope that helps.
