Collect: Survey Designer: Parent code

Hi Nancy,
as I understood the sampling design seems to be correct.
The problem can be in the way you use the sampling design code list in the code attributes.
The sampling design data works like a regular hierarchical code list. If you have 3 levels, probably you will want to use 3 different code attributes, one per level. Please try to associate them to the sampling_design code list (automatically provided by the system and associated to the sampling point data) and then specify for each of them the correct parent code attribute. You will see that the hierarchical level of every attribute will change accordingly.
I hope it is more clear now.
Thanks a lot,

I think we have to choice first root then right click , afterward we choice code, add hierarchical, albeit we must add plus bottom for several level. is it Ok?

Dear all,
The sampling point data code list is implicitly hierarchical and you cannot modify it as you do with a regular code list.
Instead what you need to do is to define two code attribute in your schema that use the sampling design as code list: in the second attribute specify the first code attribute as "parent code" so you will see the hierarchical level change to "level 2".
Thanks and let us know if this solved your issue.
