Check Box that duplicates data from one field to another field when checked
I have 2 sections on my layout containg several fields each: Legal Name, address, city, zip, etc and the other section is DBA Name, address, city, zip, etc. Often times the Legal name and address info would be the same as the DBA, but users don't like having to repeatedly type the same information on the layout. I'm looking to see if there is a way to create a button/checkbox above the DBA section that says something like "same as Legal info" that once it's checked, all the data previously typed in the Legal Name, address, city, zip, etc fields is copied into the DBA section fields.
Is this possible?
(I use File Maker Pro 11)
