weird error w Haml - Rails 3.1

I am trying display an image with the standard image_tag helper, using
options ...

= image_tag ("errors/not_found_medium.jpg", :size => "300x300", :alt
=> "error")

and I am getting a 550 error .. during haml compiling , seems not
accepting any option ( :size .. :alt .. height )

ERROR: compiling

what could be wrong ?

Try removing the space between image_tag and (
In Ruby you should not put a space there.

thanks , .. I realize that by duplicating another similar line ( copy/
paste) and changing the image url ...
looking so hard to the second part of the line I forgot the
beginning ..
