Altuit altAnswerDate

[Jim Hamlyn]

Hi Folks, 

I'm trying to use the altAnswerDate calendar widget from the Altuit RunRev
site. 

I want to use a preOpenStack script in the stack to load and save a
preferences file but this causes an error which I can't seem to overcome.
OpenCard and preOpenCard get the same error.

Any thoughts?
