Three Parameters

I have three parameters Invoice Number, City and Country.

When I select a value in Invoice Number how can I automatically get the related City and Country picked up in other 2 parameters ?

Invoice Number is a distinct value but the other two parameters do not have the distinct values.

For example:

Invoice Number     City          Country

 001                        Dallas        USA

 002                        London      UK

 003                        Dallas        USA

 004                        London      UK

So when I select Invoice Number 001 it should pick up automatically City = Dallas and Country = USA

Is it even possible ?

Thank you
