Hi,
 
I have worked out how to store cookies and retreive them in DTML to store preferences on a form.
 
Question.
If the cookie isn't there yet or gets deleted/rejected etc. How do I insert a default value into the name space?
 
What I need is something like...
if <thing> isn't there then <thing>=some default value.
 
What would solve my problems would be if <dtml-let> didn't need a closing </dtml-let>.
 
Background...
 
This cookie is used to enter a preference value in a form, thus...
 
 <tr>
  <th align="left">Batch Size</th>
  <td><input type='integer' name='batch_size:int' size=2
   value="&dtml.missing-batch_size;" /></td>
 </tr>
When the form is entered the cookie is set to the value inserted by the user, thus...
<dtml-if "REQUEST.has_key('batch_size')">
 <dtml-call "RESPONSE.setCookie('batch_size', batch_size, expires='Wed, 19 Feb 2020 14:28:00 GMT')">
</dtml-if>
 
When the user comes back to the form, the value of batch_size is magically read from the cookie as a default again.
 
Problem...
The form is called for the first time so there is no cookie. How do I set batch_size to a default value?
 
Regards,
Simon.
