Hi I'm Italian, sorry for my bad English.

I have both GL and phpBB standalone and I want to put in home page a block with recent topics.
I'm reading some topics, for example this: http://www.geeklog.net/forum/viewtopic.php?forum=9&showtopic=20904 but I don't understand much.
I receive an error in the block: funcion error; $function doesn't exist.
please help me!
