Cart help

Ok I have redone this code twice and checked it I don’t know how many times I can not find the issue any idea would be greatly appreciated. I keep getting the following erros.

Warning: Unknown: open(/var/php_sessions/sess_ee7bcd75e92f9862b20fae11902de768, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/php_sessions) in Unknown on line 0
