Hi, Can you spot the problems with the code below? I am trying to count how many instances of 'Yes' and 'No' in a column called 'opt_in_spe'

Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource

PHP Code:
$result mysql_query("select sum(if(opt_in_spe='Yes',1,0)) as Yes, sum(if(opt_in_spe='No', 1, 0)) as No");
$optin mysql_fetch_object($result);
echo 
"$optin->No";
echo 
"$optin->Yes"
