Your question is not quiet clear, but I will make some assumptions and then 
try to answer it:

I assume you want to do that all in the same file, without sending a form. 
In this case what you want to do is not possible, because you ask the 
server to know something which does not exist yet.

A form is created in the moment the user submits it. So here is how you do it:

FILE: someForm

...
<form action="someAction">
   <select name="date_dd">
      <option value="01">01
      <option value="02">02
      ...
   </select>
   <select name="date_mm">
      <option value="01">January
      <option value="02">February
      ...
   </select>
   <select name="date_yy">
      <option value="1999">1999
      <option value="2000">2000
      ...
   </select>
   <input type="submit">
</form>
...

FILE: someAction

...
<dtml-call "REQUEST.set('eventDate' , date_mm+'/'+date_dd+'/'+date_yy)">
...

So you combine your date AFTER the form is transmitted. I cannot think 
about a case, where you need it differently. If you have one, you should 
revise your design, since weird syntax is mostly due to bad design.

Stephan
