Form copy is the survey's own interface text — everything that isn't a question. It's edited
separately from your fields, in the survey's Copy section, and it's translated per locale exactly
like field labels are.
What's editable
Form title — the heading shown above the form.
Next / previous button text — shown on multi-step forms.
Submit button text — shown on the form's final step.
Button text — the trigger button's label. Only shown for popup surveys that render a visible
button; a button-less popup (Popup, no button)
has nothing to translate here, since it has no button.
Success title / success message — shown after a response is submitted.
Welcome title / welcome message / start button text — the optional opening screen. Only shown,
and only required, while Welcome screen is switched on in
Settings.
Each of these can also vary based on a previous answer (a conditional value), the same conditional
mechanism used elsewhere in the editor — most surveys never need this and can just fill in a single
default value per locale.
Before you publish
Every one of these fields must have a value for every locale your domain supports — a blank
translation blocks publishing the same way a missing field label does. See
Form types for the full validation checklist.
