open in new window

[Dave]

Have a ques. I'm not really a php programmer.. just need a little help with
"opening a page in a new window".

This is the code:

<li class="sub"><a class="sub" href="<?php echo
$TMPL['path'].'invite.php';?>"target="_blank" ><?php echo T_('Invite a
Friend');?>

Question is: what do I need to add and/or remove to the line of code so it
will open in a pop-up or new window of height=200 and width of 150
