If the user input is the value of a field in a form that was submitted,
just refer to the name of the form field:

<dtml-in "_.range(fieldname,stop,period)">

You can use the special form name syntax to have Zope cast the
field value into the appropriate type:  <input name="fieldname:int">.
There's a howto on the various possabilities for what goes after
the ':'.
