How to use FORUM URL or THREAD ID variable, to post updates on Twitter or Facebook

About posting news from using the SexyBook Marks..

Hey everyone, I am very new to this and kinda lost! I have a little problem, and I was going to make a mod using the Sexybook Marks, and it will not showe up using the Variables used on vBulletins Bookmarks, and a few other links like Twitthis.com my threads, now I am using a few others as my bookmarks showen below:

Stumbleupon Example in Bookmarks:
http://www.stumbleupon.com/submit?url={URL}&title={TITLE}

Digg Example on vBulletin Bookmarks:
http://digg.com/submit?phase=2&url={URL}&title={TITLE}

And below is the links for the Sexy Bookmarks, also used in the SexyBook Marks Plugin:

http://twitthis.com/twit?
http://www.furl.net/storeIt.jsp?u
http://www.facebook.com/sharer.php?u
http://technorati.com/faves?

I have tried to figure out how this works, but I dont know how to, if you take a look below is just an example of how this works:
http://www.facebook.com/sharer.php?u=[FORUMURL]/showthread.php?=[THREAD ID]
But i dont know what to replace the RED fields with, or what I should put behind the links, to post my threads...

I used the same term or trick in my Posts or on top of my threads, used in vBulletin Bookmakrs Like this --> url={URL}&title={TITLE} Still its not working!

I get this error from Twitthis and in Facebook nothing showes up:

Twitthis error:

You are about to twit the page:
                                                                  Link: http://url={URL}&title={TITLE}">

I did try without the TITLE and again without the URL, and many other stuff. Now I am running out of options, Hope someone could help me with this! Thank you very much in advance!
