Help with classes (oop)

Greetings, I am trying to figure out using classes. I have read and read and read about them but still cannot figure them new fangled things out. Could someone please alter this snippet just a bit so it would be a correct test script with a call to it? When I run the script I get this in my browser << Warning: Missing argument 1 for first() in /usr/~~~~~~~~~~~~~index.php on line 8 Warning: Missing argument 2 for first() in /usr/~~~~~~~~~~~~~~~~~/index.php on line 8 35chris >> As you see it does print the output. What am I doing wrong? Thanks, Leonard lbburt0@pop.uky.edu <? php; class first { var $age; var $name; function first($age, $name) { return $age.$name; } } //main script $first = new first; $test=$first->first(35, "chris"); print $test;
