st: Puzzling error with merge
Date

Dear All,
I attempted to merge two datasets, each of which has 247 observations,
with the following command:
merge 1:1 StudyID using Sheet2
(here "Sheet2" is the last part of the fully qualified name of the
file, recently imported from Excel).
I received the following error message: "variable StudyID does not
uniquely identify observations in the master data".
I then tabulated StudyID in the two files. Each output showed no
frequency other than 1 and a total of 247 observations.
What am I doing wrong?
I am using Stata 13.1.
Thanks for your help.
David Hoaglin
