Trying a new floating bar widget

Found this widget:
http://www.way2blogging.org/2012/06/new-floating-social-sharing-bar-widget-blogger-blogspot.html

So let's give it a try.

Nope.  Cannot find the <data:post.body/> tag.

I tried with the regualar </body> but the floating bar appears with errors at the bottom of the page.

Update: finally found the <data:post.body/> tag.  I miss looked ;)

But there are 4.  So testing with appending the code at first one seems to work.  However my page is not big enough to see the scrolling effect.

So adding

many

useless

lines

to

see

it

scrolling.

Update: nope.  This is not scrolling.

Checking for miss coding.  Hmm, probably miss placed code.  Should try other  <data:post.body/> ...

anyhow, not exactly what I was looking for, but close.
