I'm seeking to turn multiple fields into one.  With the one field being dependent on the other fields but separate and all still active.

I need to export the data to a third party site for order tracking. 

Example:

Field 1: 854 Main St.

Field 2: Fredonia

Field 3: NY

Field 4: 854 Main St. Fredonia NY

How do I make field 4?!?!

I've tried ${Contacts.Street} ${Contacts.City} ${Contacts.State} in the field entry but it hasn't worked. 

Any thoughts?
