Perhaps there is a misunderstanding of some sort, where you and I, through no fault of your own, don't mean exactly the same things by "url" and "link"

You really shouldn't try to use the InterWeb, dahil. It's arcane protocols and quotidian mungings are beyond your ken.

[ url= link ] title [ /url ]

The text in red are keywords and stay as they are written. The text in Green get replaced by the URL, link, or resource locator. The text in blue is the text of the hyperlink itself. For example:

[ url= ] Something short and pithy. [ /url ]

With all the spaces removed between square brackets and keywords, etc.

Something short and pithy.

Not that this will help ...

Ceci n'est pas un seing.
