URL Problems??

Hi,
I'm having what i believe is a simple error that is easy to fix i just simply cannot remember what i'm doing wrong.
I have my client area installed on a subdomain such as "www dot clientarea dot mydomain.com" now i place the url onto a designed button on my home page and every time i go to click on the client area button it sends me over to "www dot mydomain dot com/wwwclientarea dot mydomain dot com" instead of "www dot clientarea dotmydomain.com".
Now i'm sure its going to be simple fix…
