>The table contains a record for each accident at intersections in the city. Fields are an intersection identifier INT_ID, the 2 cross streets STREET1 and STREET2, injury severity INJURY_SEV coded 1 through 6. I want to obtain 1 record per intersection containing the total number of crashes at the intersection plus the total number for each of the 6 severity codes. This works for the total but I can't figure out how to add the six severity codes.

Don,

You need to add a separate sum for each of the cases, e.g.

select int_id, street1, street2, count(int_id) as crashes, ;
                sum(iif(Injury_Sev =1, 1,0)) as Total_Sev_1, ;
                sum(iif(Injury_Sev =2, 1,0)) as Total_Sev_2,  ;
                sum(iif(Injury_Sev =3, 1,0)) as Total_Sev_3, ;
                sum(iif(Injury_Sev =4 1,0)) as Total_Sev_4,  ;
                sum(iif(Injury_Sev =5, 1,0)) as Total_Sev_5, ;
                sum(iif(Injury_Sev =6, 1,0)) as Total_Sev_6  ;
	from crash1 ;
	group by int_id, street1, street2 ;
	order by crashes desc, int_id
