I have combobox,textbox and Add button on Rigth side...and Tree structure, New button on LEFT.
So when I enter some value e.g : "abhi1" is textfield with combobox value="HOSPITAL", then tree structure is as follows:

HOSPITAL
  - abhi1

But when I try to add some value e.g : "abhi1.1" with combobox value="abhi1", then abhi1.1 is added to "HOSPITAL" and not "abhi1"
It is ---
HOSPITAL
  - abhi1
  - abhi1.1

Where am i going wrong??? Pls help me add new value e.g : "abhi1.1" with combobox value="abhi1" sothat tree structure looks like ---
HOSPITAL
  - abhi1
     - abhi1.1
