As Willem said - use an array. For instance:
   <form action="..." method="post">
     <b>Specialty 1</b><input type="text" name="specialty[]"><br>
     <b>Specialty 2</b><input type="text" name="specialty[]"><br>
     <b>Specialty 3</b><input type="text" name="specialty[]"><br>
     (other stuff)
   </form>

In your target's code,

   $specialty=$_POST['specialty'];

The three (if they are filled in) will be in $specialty[0],
$specialty[1] and $specialty[2].
