Hello,
How can I use an undefined variable in an expression?
I made a DTML document which gets parameters from the URL,
like "/nieuw?maand=1".
But I also want it to work when no parameters are given.
'Missing' should be the answer, but the following doesn't work:
<dtml-var expr="_.int(maand)+1" missing=1>
<dtml-let defmaand=maand missing=1>...</dtml-let>
<dtml-in listbydate reverse size=20 start=maand missing=1>
I expected to find a solution in

but couldn't find it.
Edwin (who would be so happy with *good* documentation)

To be upset over what you don't have is to waste what you do have.
