Mike,

Cannot for the life of me get rid of this error message showing up in Preview, on all of my checkbox items, regardless whether they are single or multiple.

Here is an example of my syntax, which I think is correct:
{inline}Age:,Teen;20-24;25-30;31-40;40+;50+
But I'm still getting the error message.

What is wrong with this line?
