Hi,
I am trying to auto-populate a field based on the value user selects in another field inside the same form. I am using two data sources, both SharePoint lists.
First SP list contains information about employees and has a lookup field to the other SP list which contains information about managers.
Manager is the lookup field in the Employees list.
Employees SP list:

Managers SP list:

So, what I am trying to accomplish is to auto populate Service Line field inside the form when a user selects a manager from the dropdown list. Both fields are inside the form.

Btw, I am able to achieve this when using independet fields outside the form, but struggling how to do that when everything has to be done inside the same form.


Ty.
