Problemer med denne sætning?

$insert="insert into ".$visitors_tbl." (name, company, picture, start, end, show) values ('$name', '$company', '$picture', '$start', '$end', '$valgte')";

Dette giver:
insert into visitors (name, company, picture, start, end, show) values ('Anders And', 'Andeby', 'Billede', '2005-03-10 10:40:00', '2005-03-13 10:40:00', '2;1')

Og følgende fejl:
You have an error in your SQL syntax near 'show) values ('Anders And', 'Andeby', 'Billede', '2005-03-10 10:40:00', '2005-03' at line 1
