[Zope] <SELECT> in forms.

[Jim Washington]

Hi, Guy

You need to provide value= in the <option> tag.

Additionally, you probably should set a default selection.  Sometimes
the variable is not sent at all if nothing is selected.

As an example, if the first item in the priority_choices list is an
acceptable default selection:

<SELECT NAME="priority" SIZE=7>
<dtml-in priority_choices>
<!-- start the option tag -->
  <OPTION
<!-- here we select if it is the first item -->
<dtml-if sequence-start>
  selected
</dtml-if>
<!-- give it a value -->
 value="<dtml-var sequence-item>"
<!-- end the option tag and provide the display -->
><dtml-var sequence-item>
<!-- </option> is not necessary -->
</dtml-in>
</SELECT>

For production, you probably will want to get rid of my comments...
