I am trying to merge two data sets the common variable I want to use use is id. I get this error when combining data sets: merge 1:1 id using "C:\Users\Owner\Documents\data.dta"
(note: variable id was long, now double to accommodate using data's values)


Dataset1:

Code:
input double     id long scugrad2010 int 
100654  4940  856 4898.5269
100663 11028 1578 4957.7349

100760  2447  587 4388.7202
