hi dan,
you missed a brace (curly bracket) from the for loop
try changing to:
} else {
for ($i = 1; $i <= $_POST['guess']; $i++ ) {
$message = "Number $i\n";
}
}
also if you want to print ALL the numbers up to /including the guess
you want to use:
$message .= "Number $i\n";
(appends to $message)
not
$message = "Number $i\n";
(assign to $message)
cheers,
ED
