Fout met query :You have an error in your SQL syntax; check the manual that corr

Ik krijg deze fout:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '= '1' WHERE name = 'tdr93'' at line 4

Met deze query:
UPDATE users SET
money = '" . $money . "' ,
skill = '" . $newskill."' ,
" . $item . " = '1'
WHERE name = '" . $_SESSION['suser'] . "'

Wat moet ik veranderen?
