Help using test in alround automations PL/SQL Developer

Question

hi sory if this is a bit of a beginer question, Im trying to test the folowing package using the test window in pl/sql developer.
I was expecting to give the test a value for var_detail_id which it askes for so is good :) , and the test to return the value of v_Media_Object_Name. which it dosent.
and i dont know enough to know if there is a fault in the code or a fault in the way i am using the test utility. ive put the select on to a sql worksheet, and it returns a sensable name for the detail_id i give it.
any thoughts on why the test utility dosent return the value of v_Media_Object_Name?
thanks
james

Your run_report procedure returns nothing to the caller. You must either have an out parameter return the value selected or make it a function that returns the value expected by the caller.
As it is, there is nothing that is returned. So, no client, including PL/SQL Developer, will be able to display any results.
