Initials automated in field

[JacJS]

I was hoping someone might be able to help me create the following calculation in Filemaker Pro Advanced 8.5:

I have 2 fields: "First Name" and "Surname".

I was hoping to create a separate field that automatically entered the initials of the name, eg. John Smith = JS

What formula do I need?

Please help.

Left ( First Name ; 1 ) & Left ( Surname; 1)

However, you'll probably have problems with people who are named: Cher, von Blout, de Ville. Derived initials can be tricky.

Thanks very much!
