----
if the variable $memberid contains a zero, and you use:
if($memberid != '') ....
the outcome is false because somehow '0' becomes '' (empty) somehow
i found a solution for this:
if("$memberid"!='') ....
the above expression will distinguish between 0 (zero) and '' (empty string)
it cost me 1 nightly hour so i hope it helps someone else
