I have a form where I have to have the following info on the top left corner of the form for our clients:

TO:Name of client
Address, city, zip...
Phone number
Fax Number

I need to find a way to create a drop down list where I have my contacts information so that if I pick a name, it will show up on my form but also have the address, phone....in the format as above so that I don't have to keep inputting the information manually as there are over 20 names, any ideas?
