It is not possible to use Repeating Data structure or repeated measures in surveys. Please consider the following alternatives for Repeating Data/repeated measures in surveys:

Please note that it is advisable that the dependent fields are located on the same page as the question on which they are dependent. If the dependent fields are located in a different step without any other fields, the step will be shown as blank. If you opt out for this option, you could add a remark field to instruct the respondents to proceed to the next page.
