hi Anusha
there are two situation base on what kind of data you want pass to Adobe form?
One:
-Level 1
--Level 2
---Level 3 when you select Level3, actually you want pass data of Level1 to Adobe form.
Two:
-Level 1
--Level 2
---Level 3 when you select Level3, actually you want pass data of Level3 to Adobe form.
