right... I had tried before with a semicolon between the two set clauses... using just a comma.. this compiles with no errors;

delimiter GO
drop trigger if exists calculate_time_rate;
CREATE trigger calculate_time_rate
BEFORE INSERT ON admin_time_tracker
FOR each
ROW
BEGIN
SET new.elapsed = ( TIMESTAMPDIFF( MINUTE , new.start_time, new.end_time ) / 60.00 ),
new.amount_due = ( new.elapsed * rate ) ;
END;
GO
delimiter

but when I try to in sert a new row I get this error now:

insert into HA_ADMIN Admin_time_tracker
id
developer
data
project
task
description
starttime
endtime
elapsed
rate
amount_du
doc_link
task_id
project_id
