Point to Domain

hi I got wordpress…it seems to install great when i import it to a folder on my domain such as :
Mydomain.com/wordp
However I want it to show up when the viewer goes to “www.mydomain.com” … which is “www.alphavillgazette.com” … When I do that, not works and I Get some error and the link changes to:
https://alphavillegazette.com/wordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordpwordp”
a) How do I get it to work properly under the domain
Thanks! ?? Ian
