Just what I was looking for...

When I had looked on php.net/call_user_func for this situation I saw
the example and misread it as not having the arrays - rechecked after
your post and my eyes are seeing it now... (that or the evil gremlin
that sneaks in my code is now messing with other people's sites
too... )

Thanks,
