Well if that's the complete code, there is no form tag or submit button.
If you have those (and just haven't posted them here)
$_POST["secretAnswer"] would be set anyway from a POSTed form (unless it
was something like a checkbox or radio button). But it would be empty.
See Rik's second example.

If you are posting the form to itself you may get an error notice at
first (with full error reporting). In which case:

if(isset($_POST["secretAnswer"])){
$secretAnswer = $_POST["secretAnswer"];
}
else{
$secretAnswer ="Form not posted";
}
if(!empty($secretAnswer)) {
echo $secretAnswer;
}
else {
echo "No value posted";
}
