Adding a Facebook 'Like box' to my website, where am I going wrong?!?

[Cherry]

Hi, I wonder if anyone can help me. I have a facebook page for my Face painting business and also a website which I designed myself using Dreamweaver, I have found the section for facebook to get the code for the like box http://developers.facebook.com/docs/refe.../like-box/ and have put my details in and generated the code, however once I have this code, I have tried the options under 'HTML5' and 'IFRAME' and 'URL' and can't get any of them to work to bring the like box up on my page, I am doing what it says and copy and pasting in the code but am I missing something else I should be doing too? Any advice appreciated :o)
Hi Drew, that is very kind of you to offer, it seems that I have managed to do it by trying to put it live! Think initially I was trying to put it in too small a gap and then I thought it wasn't working but that was just in preview, it worked in live :o) I will choose you as best answer when it gives me the option - thank you!
