Importing Data

Importing Data

Hi can anyone help please
 
Ok so here is the setup
 
Lets say I have a form callen "customer" with fields called "name", "age" and "telephone number".
 
Now, I want to create a second form where I insert a lookup field from "customer" using the field "name"
 
Here is my problem, how can I make the second form automatically show the "age" based on the "customer" I choose?
 
What I am trying to do is create a database where on the repair ticket, I only have to choose the customer name and other selected fields will automatically show.
 
Hope this makes sence and hope you can help.
