Hi Sayali,

Is the code shown above *everything* in your Project.hs file?  You
will also need a main function for it to actually do anything.  If
there is more to your Project.hs file that you have not shown, could
you send the complete version?

Do you get any errors?  Does Project produce the output that you expect?
