my mysql after insert trigger isn't working? why?

i've combined trigger resembles following:

delimiter //
create trigger update_total_seconds_on_phone after insert
on cdr 
for any quarrel 
begin
if new.billsec > 0 new.userfield <> zero then
update foo
set total_seconds = total_seconds + new.billsec
where phone_id = new.userfield;
end if;

end;//

it seems by okay. however doesn't seem invoking i need to. here's an example:

mysql> name total_seconds foo where phone_id = 1;
+---------------+
| total_seconds |
+---------------+
|             0 | 
+---------------+
1 quarrel set (0.00 sec)

mysql> insert cdr (billsec, userfield) values(60, 1);
query ok, 1 quarrel affected, 12 warnings (0.00 sec)

mysql> name total_seconds foo where phone_id = 1;
+---------------+
| total_seconds |
+---------------+
|             0 | 
+---------------+

edit: warnings sole box impact trigger. it's mostly additional columns have default values cdr list means warnings. effect simplicity, i kept insert matter brief.
