PHP update mysql table, subtract by 1 -

i trying ticketing system. when user has registered successfully, subtract available ticket seats 1. $availseats = $_post['myavailseats']; //3 //once registration info entered, minus available seats $sql = "update tblcourseinfo set availseats = --$availseats courseid = '$courseid'"; however when statement queried, availseats updated 0 instead of 2 . data type int availseats . why happening? edit: thanks helped me. here solution has provided: $availseats = $_post['myavailseats']; // 3 //once registration info entered, minus available seats --$availseats; // decrease seat 1 first $sql = "update tblcourseinfo set availseats = --$availseats courseid = '$courseid'"; if availseats had value, subtract directly mysql may work: $sql = "update tblcourseinfo set availseats = availseats - 1 courseid = '$courseid'"; or subtract $availseats before query.
