Hi all! Bit of niche issue here, so bear with me please.
I have a repeat group in which enumerators can enter the name of water sources in a village. The relevant variable is source_identifier. The calculate variable safe_source_name filters for sources that are safe to access.
At a later stage, I have another repeat group, which repeats for each water source that the enumerator is accessing. Each time the group repeats, they can select which of the water sources they are accessing, see here:
All this works just fine. However, enumerators should only access each source once, so I want to avoid them accidentally selecting the same source a second time when the group repeats.
