world of CS50!

Having issues passing check50's tests for mario. I looked at other issues, including ones that look the same as mine, but I haven't found a solution.

My code seems to give the desired results as shown on the pset1 specification page. I also entered 0, and a white space and my program rejected them and asked for input again.

My program's output:

Height: -1
Height: -2
Height: foo
Retry: bar
Retry: 1
##
Retry: 8
       ##
      ###
     ####
    #####
   ######
  #######
 ########
#########

However, when I run the check50 I get this:

jharvard@appliance (~/Dropbox/pset1): check50 /2014/x/pset1/mario mario.c
:) mario.c exists
:) mario.c compiles
:( rejects a height of -1

I searched for TERM environment variable not set.\n, but found nothing.

What am I missing here?

Thanks for looking, I appreciate any help :)
