Adding data collectors

I have been having my form running well and i have been adding users/data collectors whenever need be. but of late i have not been able. how best can i have this sorted.

Hi @mbselijah,

Welcome to the community! Could you share how you added users/enumerators so that we could have a look at our end and see if its a system error you are facing. Would appreciate if you could use image as far as possible as it would be easy for everyone to understand.
