Test Plan Module Script

Dear,

I am trying to write code for following scenario and unsuccessfull so far.

In Test Plan module I have the test case in following folder structure:

FRUIT   <- Parent Folder

     APPLE   <- Sub-Folder 1

           RIPE   <- Sub-Folder 2

                  Test Case 01_Test the ripe apple    <- Test Case

I have created a new user field for Test module i.e. "Project".  Now, with the Test Plan Module Script code in Test_MoveTo, I want to update the "Project" field in the Test Case: "Test Case 01_Test the ripe apple" with the top most parent folder name i.e. "FRUIT".

Please advice me here.

Thanks,

Tanmay
