Hi

I ran the following code.

Code:
foreach y in 2003 2004 2005 {
      foreach s in 3 6 8 15 27 33 {
      local st: label state_64 `s'
      xtile course_10_`st'_`y' = course if state == `s' & year == `y'  , nq(10)
      }   
}

It runs for the first inner loop : i.e. y = 2003 and s = 3,6, 8 ,15 ,27, 33

and then shows the error:

too many variables specified
r(103)



I am not sure what is wrong.
