Merge files in STATA
pHi I am using STATA 12 and trying to merge two files with variable ID,
the ID is not unique in the file I am using, but it is in the other file
so I use the syntax:/p precodemerge m:1 ID using massi.dta /code/pre pBut
I always get the following error message:/p pvariable ID not found
r(111)/p pAnd I am sure that the variable ID are in both files and I have
been trying to figure this out without success, can anybody please help
me?/p
