Form Field - Drop down selection causing auto text

[chesspupil]

I do inspection work on submarines that must be documented. Each Boat has it own ID code that I would like to appear in another are of the form based on what boat I select from a Form filed drop down list.




Please see the attachment:

Block one I select a boat in the drop down. In block 2 I would like the first 5 numbers to automatically appear based on the selection in block 1. Currently they are in matching order but it is easy to mis-select the wrong 5 digit number if you are not careful or familiar with the layout.

I have no preference for how its done, just that it works...(VBA or Macro)
