Is the error caused by the missing "$" before "result"?

<?php
$result = mysql_query("UPDATE controle set chave_nei= chave_nei + 1");
?>

If not, what is the error you are receiving?

 

 

Side note: the mysql_ functions have been depreciated. If you're not doing so already, you should start looking into the alternatives:
