Hi All! 

I have a text field from which I'd like to get the initials. I have the following properties in  my model:

1. Firstname => This is the first name

2. Lastname => This is the last name

3. Full Name => This is an expression combining the two names

How would I go about getting the initials from here and storing them within my backoffice? I can't really find any documentation on this or any expression I could use.

Thanks in advance!
