Welcome to PHPBuilder! When posting PHP code, please use the board's [noparse]
..
[/noparse] bbcode tags (not the generic CODE tags) as they make your code much easier to read and analyze.
As for your issue.. you've shown us some code, but you haven't explained what's happening versus what you expected to happen.
One problem I notice is that you have a space before and after the colon as well as the '@' symbol in the URL; URL's can not contain any spaces.
