Re: ->

<? class generic { var $test_1; var $test_2; function set_var($var_1, $var_2) { $this->test_1 = $var_1; $this->test_2 = $var_2; } } $something = new generic; $something->set_var(10, 12); echo $something->test_1 . "<br>\n"; echo $something->test_2 . "<br>\n"; ?> all classes do is organize data, its a nice way of doing it too. all the -> is access that data/function. Im not quite sure what you mean when you say "generic-> becomes something twice" as far as I can see, nothing is becoming nothing. Chris Lee Mediawaveonline.com ""Karl J.
