Workflow Rule: Update Pick List in Contacts from Pick List in Custom Module

Workflow Rule: Update Pick List in Contacts from Pick List in Custom Module

Hi, 

I'm trying to setup a custom function that would sync identical pick lists that I have in 2 separate modules, from a custom module to the contacts module.

List Fields are called "Type" and "Status" (API Names are identical, too)
My custom module has the API name: Intermediaries

Currently struggling to get the syntax right.

Anyone would have a sample code I could try it on? 

I browsed through a lot of posts, but none of them seems to do what I need. 

Thanks!
