Ihis didn't work, then? Looks better than what I came up with, which, for the list vs. string situation goes like: <dtml-try> <dtml-in string_or_list_var> list stuff... </dtml-in> <dtml-except> non-list stuff... </dtml-try> If you have a string with multiple values to split, use the _.string.split() function, as... <dtml-in "_.string.split(str [,separator])"> This will probably choke on lists, though. Combine the two for a wholesome, good-start-to-your day breakfast code. :-)

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. My initial thought was to do this:

<dtml-if "type(var) == type('')"> ... (do not iterate) <dtml-else> <dtml-in var> ... </dtml-in> </dtml-if>

How can I either cast a string to a list w/o messing up an existing list, or gain access to Python functions such as type() from a dtml-if statement?
