Prevent form field from being modified

I'm relatively new to Javascript, and I've managed to create a "calculator". The thing though is that the only method I know of to display results is in a TEXT field in a FORM. My problem is that it is possible for the user to go into these text fields and edit the results (for whatever reason) and may cause some confusion. So I would like to know if there is a way to prevent the field from being modified (no, not willing to do something like send the values to the fields every half a second). If not, then is there any other way to display answers in an object other than a text field in a form?? If you would like clarification of what I'm talking about look at it at: http://courses.bus.ualberta.ca/mgtsc352/2_5_clc6.htm 
The only thing the user is supposed to modify is the field beside "SMOOTH".  Thank you!

Change each of the input boxes that you calculate to (for example)

<td><input type="text" name="f2" size=4 OnBlur="compute(this.form)"></td>

Then as soon as the cursor is moved off the field any changes are recomputed.

Of course it will not change it back until the cursor moves off the field but then no other solution will either.
