Android code challenge not working properly

Either I've gone blind or this challenge doesn't work properly. Task 2 is to set the variable to View.VISIBLE, which I've done and which passes, while task 3 is to add an else-statement in which the variable is set to View.INVISIBLE, which I've also done, however no matter what I try, it doesn't pass.

InviteActivity.java 
// unimportant code emitted
    public OnItemClickListener mOnItemClickListener = new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            // Start by adding code in here!
          if (mGridView.getCheckedItemCount() >= 0) 
            mInviteMenuItem.setVisibility(View.VISIBLE);
          else 
            mInviteMenuItem.setVisibility(View.INVISIBLE);

        }       
    };
}

Ah, never mind, I solved it. The equal-sign is why it failed. The compiler didn't realize my mistake, and I was equally blind to it, heh.

The correct answer is:

if (mGridView.getCheckedItemCount() > 0) 
       mInviteMenuItem.setVisibility(View.VISIBLE);
else 
       mInviteMenuItem.setVisibility(View.INVISIBLE);
