That's great, thanks. That's almost exactly what I had except I had put
brackets on the end of the get_elements, so I couldn't get it to work.

That works great! Thank you. How do I count the number of elements returned
by the get_all_element function?
$form->get_all_element({ type => Repeatable })
If I display the variable, I can see that I get four elements, but I don't
know how to count them with code.
"get_all_element" will only return the 1st item that would otherwise
be returned by "get_all_elements".
The "all" just means it works recursively.
So in your case, "get_all_element" should be returning a Block, which
itself contains some number of elements.
It's not very pretty - you have to dereference the array-ref to a
list, then count it in scalar context:
$count = scalar @{ $form->get_all_elements({ type =>
Repeatable})->get_elements };
Hope that helps,
Carl
