odd bash script problem

[Ben Luey <lueyb@carleton.edu>]

I'm new to bash and I'm trying to write a little script to load a new
window of netscape if I type newnetscape usr new and a act normal
otherwise here is the script:

#!/bin/sh

if [ $2 = "new" ]
then
     netscape -remote "openURL ($1, new-window)"&
fi
    netscape -remote "openURL ($1)"&

It works except when I don't have new as $2, I get the following message

[lueyb@pcLueyB /]$ newnetscape http://www.linuxnow.com
/usr/local/bin/newnetscape: [: =: unary operator expected   


What's wrong?

Thanks,
Ben
