I have never tried tying a method to an html select tag, but I would guess
that the browser would just return a string variable (in your case the form
variable name would be 'form_action_type') containing the result of your
dtml-var tag.

What you may want to try is setting the value of the select options to a
flag value which you test in a zope method to control your redirection.

eg.

<form method="post" action="form_action_method">
    <select name="form_action_type" size="1">
       <dtml-in lookup_action_query sort=school_name>
          <OPTION VALUE="<dtml-var sequence-item>"><dtml-var school_name>
<dtml-var sport_type></OPTION>
       </dtml-in>
    </SELECT>
...

</form>

You would have a dtml method called 'form_action_method' which checked the
contents of a variable called 'form_action_type' which then takes some
action (ie. redirect)

This assumes that 'lookup_action_query' is some type of sequence that
dtml-in can loop thru.
