Ok, I am a beginner and I wrote this script. I dont know but it gives me a notice of "Undefined Index" for all the variables that I have declared here. Please look through it.

 

<html>

  <title>A silly Poem</title>

  <body>

  <h2><u><i>Enter the following to read a story</h2></b></i><br><br><br>

  <form method="post"

  action="poem.php">

  <h4>Enter your name:

    <input type="text"

    name="UserName"

    value=""><br>

    Enter your age:

  if ($Sex=="boy"){

  print "Once upon a time there was a boy named $UserName. He was $Age years old. $UserName 's favorite color was $FavColor. He had a pet $FavAnimal.

  His best friend's name was $Friend. One day, they both went to watch $FavMovie together. To their surprise, they saw $FavActor.

Please use 



 or 




 tags around the code you post.


 



The undefined indexes are UserName, Age, Sex and so on in the $_POST array. They are undefined (not set) when the form hasn't been submitted. You can simple put the PHP code inside a conditional statement checking that $_POST is not returning false:

Or use !empty($_POST) as FD_F suggests. But you can't use isset($_POST), since the $_POST array always is set.
