Right... Line 12 + 17 - variable 'submit' undeclared. You should use the following:

function showHide()
        {
            if(document.getElementById('Checkbox1').checked == true) // If the checkbox is already checked
            {
                document.getElementById('submit').disabled = true;
            }
            else // If the checkbox is not yet checked
            {
                document.getElementById('submit').disabled = false;
            }
        }

And in your form:

<input id="Checkbox1" onclick="showHide(); return true;" type="checkbox" />

If this does not work, perhaps you should alert() the variables you retrieve out of the HTML using getElementById()...
