But I'm not sure, so you should check that out. You should check $count for existence btw, before you register it as a session variable. Ca. it's already registered as a session variable. Then you don't want to register it again. And besides that, what would you think of initializing variables? I mean... you increase $count[0], but from which value? I'd say something like this: --- PHP code --- session_start(); if (!isset ($count)) { $count = array(); $count[0] = 0; if (!session_is_registered) { session_register ("count"); } } $count[0]++; --- End of PHP code --- </Reply> -- * R&zE: -- »»»»»»»»»»»»»»»»»»»»»»»» -- Renze Munnik -- DataLink BV -- -- E: renze@datalink.nl -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- Netherlands -- -- http://www.datalink.nl -- ««««««««««««««««««««««««
