Change language of buttons

I would like to change the language of four items in the form, from english to czech:

  • next
  • Return to beginning
  • Go to end
  • this field is required

Where can I change this?

@Eline, are you collecting data through the Collect Android App?

No, just via the web form

If you are on Chrome and wish to change the language from English to Czech for a web form, you could right-click your mouse when you are on the data collection page and then select Translate language to your default browser language. This site should also help you change the default language for your browser.
