Can you do attribute referencing with colon notation for objects within slides?

Adam,

I may have a workaround for you.  Let's suppose your Reference 
attribute is in a nested list (and if it's not, then it really should 
be).  For the sake of discussion, let's call your main list 
TrialList, the nested list NestList1, and your slide 
StimSlide.  NestList1 contains the attribute (column) Reference, 
which you want to use with colon syntax in a SoundOut sub-object on StimSlide.

So, simply add another attribute (column) to TrialList, let's call 
that MainReference.  Then use your colon syntax to have MainReference 
refer back to Reference in NestList1, e.g., [Reference:0].  Now in 
your slide sub-object, just use a straight reference to 
TrialList:  [MainReference].  So you do not use any colon syntax in 
the slide sub-object -- the slide sub-object refers to MainReference 
in TrialList, which in turn refers (via colon syntax) to Reference in 
NestList1.  Whew!

I tried this and got no errors.  So please give this a try and let us 
know how it goes.

Thank you for an interesting and challenging question,
