Hi Mario,
I am happy to inform you that I solved my problem. All what I needed was a
counter hidden field count and a counter_name: count in the repeatable.
Then when building my hashref, I set the value of count to
scalar(@{$hr->{my_rep}}), and now it works flawlessly. All repeated blocks
are recognized. Every error in each block gets the error message displayed
aside itself.
Thank you so much for your attention.
