Paul,
Where are you having the problem? Converting the text to an integer,
constructing the string, using the onchange event, updating the value in the
form field below to contain the string of spaces, or what? Hard to know
what you are missing when you don't say what you have. Writing a complete
answer for you without more information would probably be doing you a
disservice (this sounds like it might be homework related?).
