Customer selection in Word

[Jackissimus]

Hello from the Czech Republic,



first let me show you what I want. I want to choose a customer in one form field and then let Word fill the other form fields for me.





There are not that many customers, but the number is growing. I am a service engineer for a small company and these are service reports I have to fill after every service. This type of automation (there are others) would help me very much.

I don't know anything about macros or anything else, but I am willing to learn everything I need, just tell me how do you think this problem should be approached.
