It strikes me that you have left the 'the' out of the 'get' statement, 
since apparently you're referring to a custom property; but in terms of 
indirection you're working too hard as the engine itself will evaluate 
'theGroup' and use its contents. So your 'get' line should read:

  get the actionStepDueDate of group theGroup

Then I think it should work. Seems to work here, anyway. If you want to get 
any more indirect than this, use a 'do' statement, which evaluates a string 
before executing it.
