coding/placing a facebook button

I have tried in vain and can't seem to get this to work. I am also not very good at websites.

I am trying to place a facebook like button, but don't know where to put the code. I try to place it next to or in a table, but I can't see it in design view. When I upload it to my webserver, it appears anywhere on the page, if even it appears.

Can you give me some advice. I can get the twitter button to work fine.
