Test Type Edit bug fix. Fixes #3. Bug was generated by commit 9cd4e28.

@kitsao please review my code.
I've made changes to the htdocs/catalog/test_type_edit.php file on lines 338 to 340 to revert to what thet were before commit 9cd4e28.
Please verify that these changes do not break any of the new features you had subsequently introduced.
