Another question (soon I'll start answering more on this list :) - I have a set of checkboxes with the same name that I iterate through using dtml-in. However, when only one checkbox is checked, dtml-in complains that a string cannot be used as input, it expects a sequence.
You can specify ":list" in your checkbox code to typecast the input. Here is a quick test. The list should display OK when one checkbox is checked. <FORM method="post"> <INPUT type="checkbox" name="myList:list" value="First">First<BR> <INPUT type="checkbox" name="myList:list" value="Second">Second<BR> <dtml-if btOK> <dtml-if myList> <SELECT name="myList"> <dtml-in myList> <OPTION><dtml-var sequence-item></OPTION> </dtml-in> </SELECT> </dtml-if> </dtml-if> <INPUT type="submit" name="btOK" value="OK"> </FORM> For more info see this howto: <http://www.zope.org/Members/Zen/howto/FormVariableTypes>.
