During the setup of a survey, it is possible to make quick and easy modifications by switching between Test Mode and Edit Mode.
After a survey has been published, it is no longer possible to edit your survey by switching survey modes. The reason that we lock down the survey after it has been published is that the survey on the device must match the survey in the Data4Action database in every way. If it does not match, the results will not map to the structure in the database and the results will be useless. The solution to this restriction is to duplicate your published survey, edit the duplicated survey and then republish it.
After editing and re-publishing, a survey, the results from your original survey and results from your re-published survey are stored in separate files in your Data4Action account. This means that you will have to download these files separately to obtain all the results for your project or campaign.
We recommend you test your survey on a physical device before publishing / purchasing a survey. If required use the Edit a Published / Purchased process sparingly to reduce the fragmentation of your survey results.
