A search from my input form returns no results from the database! An
exact match for "recipe_name"; for example: "fiskgryta" - only returns
a blank page! This should be a transformation from "php" through an
"xsl-stylesheet" and generate a nice html page of results. Please
refer to:

http://www.student.nada.kth.se/~u1j80hrt/2D1517/XMLprojekt/

to access all of my files!  I might add that this is ALL new to me!
Thanks in advance :)

Here's my "search.php"-file:
