Hello
i wanted to add some user information
So i created a new module and add the module_user() function

Any help?
Here is my code

function module_user($op, &$edit, &$account, $category = NULL){
	if ($op == 'view') {
	$output="<table class=data><th>data1</th><th>data2</th><th>data3</th>";
	foreach ($trans as $mv){
		$output=$output."<tr>";
		$output=$output."<td>".$mv[0]."</td>"."<td>".$mv[1]."</td>"."<td>".$mv[2]."</td>";
		$output=$output."</tr>";
	}	
	$output = $output."</table>";
	drupal_set_message($output); 
	}
}
