well at the moment when the code runs it just puts the value held by the 'tokens' variable into the earnings row.and doesn't add it to the current amount.

im geting variables from flash using php.but i dont know how to use them variables in these statement... $placeEarnt = $_POST['placeEarnt']; $earnings = mysql_query("SELECT '$placeEarnt' FROM users WHERE username = '$username'")or die(mysql_error()); if(mysql_num_rows($earnings)==0) echo "There is no data in the table"; else for($i=0;$i<mysql_num_rows($earnings);$i++) { $row=mysql_fetch_assoc($earnings); } $updateEarnings = $row[earnings] + $_POST['tokens']; $result = mysql_query("UPDATE users SET $placeEarnt ='$updateEarnings' WHERE username = '$username'") or die(mysql_error()); this doesnt throw an error but only adds the value in $_POST['tokens'] to the database.does anyone know how i can make this work?thanks
