I have a dropdown field with a Yes or No values. I assign 1 & 0 values to the dropdown for Yes & No

When the form loads it has one field which is the above dropdown values.

If the user selects Yes , submit button should be hidden and the user is displayed a message .

If the user selects No submit button should be visible and the user should be able to submit the form.

Below is what i have and it doesnt seem to work. 

$(function()    
  {
    alert("Code triggered");
      if ($('#q2 input').val() == 1)
    {
         alert("Submit Disabled");
      $('.Submit').hide();
    }
   else
    if ($('#q2 input').val() == 0)
      {
      alert("Submit enabled");
       $('.Submit').show();
    }
  });

Anything incorrect in the above?
