New Post: Blog: change width Facebook like button

In the BLOG we have a Facebook LIKE button. But because the language of the site is Dutch the like button is translated to 'vind ik leuk'. The width now is to small so the number of likes is not visible. Take a look.

The solution is pretty simple:

So I have to add a simple thing: fb:like:width="115"

I can change it in the FUNCTIONS of Composite C1:

APP_data >> Composite >> Community >> BLOG >> Blogrenderer.xslt

But when i change it the I get an error:

Error: The ':' character, hexadecimal value 0x3A, cannot be included in a name. Line 163, position 52.
C1 Function: Composite.Community.Blog.BlogRenderer
Error details:
The ':' character, hexadecimal value 0x3A, cannot be included in a name. Line 163, position 52.

thanks for your reply. (I am a newby on Composite C1, but we like it)
