Automatically attaching Lookup fields

Automatically attaching Lookup fields

Hello, 

So, I am trying to automate the attachments of lookup fields depending on the program that the contact is assigned too. There are 3 possible options for programs and then each program has multiple faculty that it needs to link too. So I need them to work with IF statements, but I'm having trouble figuring out how to create it.

This is what I have so far:

contactMap = zoho.crm.getRecordById("Contacts",contactId);
info contactMap;
updateMap = Map();
If "Program" = SUD;
updateMap.put("Supervising Faculty", Vanessa Garcia)

I think I'm using the IF function wrong, but I'm not sure how to fix it.

Thank you for any assistance you can give!
