Counting obs (Update)

[GreggB]

My previous post tells me I clearly did not have an accurate picture of my data.  Earlier, I had said I wanted to count the number of ssn in the data.  My objective was to determine the number of absences for each teacher.  My approach was short-sighted.  Consider "Smith."  It appears he was absent 4 days but this is not so.  Smith works at two different schools (Park and West)  so each school reported the absence for Jan 22 and 23.  He was only absent 2 days.  I need the count of each teacher's  ssn BY school.

Obs	school	ssn	last	date
1819	Fair Elementary	1443	Jones	12SEP2014
7587	Blue Elementary	7369	Brown	25NOV2014
8661	Park Elementary	0976	Smith	22JAN2015
8662	Park Elementary	0976	Smith	23JAN2015
8665	West Elementary	0976	Smith	22JAN2015
8666	West Elementary	0976	Smith	23JAN2015

This code gave me the total for school = Park but there's nothing for school= West.
