Dynamic Drop Down menu not working.

Hey guys! How are you?

I know that this topic has been discussed many times. I swear that i have read them all but even with that i cannot get the solution or a clean explanation about how to perform this.

Basically what i need is as the subject says , get the dynamic drop down menus working.

I have two fields: LBL_GDE and LBL_RUBRO.
LBL_GDE is the father and LBL_RUBRO is the child.

LBL_GDE values:

  • UCC
  • NET
  • SEC

LBL_RUBRO values:

  • UCC_data1
  • NET_data2
  • SEC_data3

So what i need basically is to have “NET_data2” in the LBL_RUBRO field when in i choose “NET” on LBL_GDE dropdown.

In one of the many discussions raised, i read that in the father field from the dynamic dropdown menu , you should put the father’s field name within the module context. So thats what i did, but i’m afraid that on the dynamic field (LBL_RUBRO), nothing appears (it gets blank).

I attach the screenshots so you can check it on by yourself:

Thanks to all !!

The list values needs to be UCC_data1, UCC_data2 etc, not the display label.

I was doing it in the opposite way, thanks!
