Hi Scott,

You need to add this to your Repeatable element:

model_config:
    empty_rows: 1
    new_rows_max: 1

I've used YAML, in case the Config::General tags get hidden in your email
viewer, but I'm sure you'll be able to translate them.
'empty_rows' displays the fields to add a new related row, so isn't strictly
necessary, depending on how you're rendering your form.
'new_rows_max' is the important setting, and will default to the value of
'empty_rows' if it's missing.

Carl

Carl,

Having struggled with this for weeks I am utterly delighted to now have a
working prototype.  Thanks.

Scott
