Database trigger cannot read the updating table

Question

I want to create a database trigger :
after insert or update on EMP
for each row
begin
select sum(EMP.salary) from EMP WHERE .....
end;
However, I got an error is that I cannot read the updating table if the trigger is 'for each row'. Can anyone help me to to this?
More, I must use 'for each row' trigger for this case.

I think the SQL statement should be
strSQL = "SELECT * FROM MaterialLotJobJoint WHERE JobID=" & _
tempvars!JobID & " AND MatLotID=" & tempvars!MatLotID
This assumes thatJobID and MatLotID are number fields.
