issue with SELECT settval(..);

["Alain Roger" <raf.news@xxxxxxxxx>]

Hi,

I would like to auto increment my sequence when i'm going to insert a new record into my table.

for that i wanted to use : 

insert into immense.statususer (statususer_id, statususer_type) values (SELECT nextval( 'statususer_statususer_id_seq' ),'customer');

however, i get an error message in pgAdmin III, as following :
ERROR:  syntax error at or near "SELECT" at character 168

i do not under because if I run SELECT nextval( 'statususer_statususer_id_seq' ) alone, it works perfectly and increment the sequence.
moreover, everything regarding the table is correct. so where is the problem ?

thanks a lot,
