		 Good morning Dear Members of DHS 
 
I would like to merge DHS with Children Data 
 
First in children data i created this variable : egen new_cluster_ID = concat(v000 v001), punct(-) 
Then , in GPS data, i creayed the same variable: egen new_cluster_ID = concat(DHSCC DHSCLUST), punct(-) 
 
After that, i apply this command:  merge 1:1 new_cluster_ID using "C:\Users\ndjak\OneDrive\Bureau\Merge\base_finale.dta" 
 
but i received this message: variable new_cluster_ID does not uniquely identify observations in the using data 
 
I do no know how to do, please can somebody help me? 
 
THank you, 
Manou
