Get a Integration Dropdown Field

Get a Integration Dropdown Field

Hello,

I'm trying to do a simple thing, get the name or id from a integration field (integrated with my potential on my crm), the field works fine, gets all the names of my potentials.
But im testing a way to get the id or name of the selected potentential on the selected name on the drop field and it says always that its null.

I really need help in this.

Check the prints:

print 1
print 2
