looks  like the variable  that you are using in <dtml-in ...>
is noat a sequence (list || tuple)

I suppose that your var is a dictionary

Insted of :
<dtml-in x mapping>
you have to use:
<dtml-in "[x]" mapping> as a list
<dtml-in "(x,)" mapping> as a tuple

 and if the answer is "yes"
 I know that it's going to be a good day.
