Apologies - I misunderstood. I have applied your code and the datepicker is now repeated.
However! As soon as I apply the DA Multiple Insert, I get:
ReferenceError: translatedString is not defined.
and the datepicker no longer appears on ANY of the repeated date fields.
I've had this error before and you needed to alter something on my machine (working on my laptop now, so perhaps this needs altering too?)
