How to use string from condition1 into condition2?

I have the following code:

<form action='' method='POST' id='form1'>
    imdbcode :  <input type='text' id='imdbcode' name='imdbcode' /><br/>
           <input type='submit' name='submit' value='Get'/>
 </form>
<?php
 if(isset($_POST['submit'])){
.
.
.
$title = ... ;


 echo "
 <form action='' method='POST' id='form2'>
           <input type='submit' name='Send' value='Send'/>
 </form>";
}

if(isset($_POST['Send'])){

//I WANT TO USE $Title from condition1 

} ?>

I want to use $title in second condition.

It prints $title in first condition! But doesn't print after closing condition!

How can I do that?
