I'm a little confused on this statement.  Why will it throw an error when
checking the length of a value?

I think if you look back, you'll see that I suggested something similar
since all js-enabled browsers wound (should) be able to handle. I even
suggested that you alert the user of why it reverted to the original value.

Now if you wanted to take this one step further - at the risk of having the
code rendered useless in some browsers - you can add custom attributes to
that element and read those in the onChange event. Something like
isDisabled="true" originalValue="4" or something along those lines.
