Tips and tricks
Survey changes in multi-wave studies
Adding a new question or dropping an old one in new waves is fine. However, you should not re-use previously used question numbers and column names for different questions. See update project data for more info.
Set your project to automatically turn [NA] values off
Our default is to show the [NA] values globally. You can show/not show [NA]s on a per-element basis. The attribute in JSON is "showMissing" : true or false. However, you can add a small snippet of code in pre-calculate to set "showMissing" to false globally on opening of the project.
if (typeof protobi.viewModel !== 'undefined'){ protobi.viewModel.set({'showMissing': false})}
return rows;
