Help on how to display 1st & 2nd values in list on layout

[Jerry100]

I have two tables Discipline & Disposition. I created a value list using the records from the Disposition Table. I want to use a drop down list to populate up to six Dispositions on the Discipline Layout. When I use it on the first occurrence, both fields from the value list appear. When I try it on the second occurrence, only the first field populates. Seems like a common use of value lists, but cannot figure it out.

Thank you in advance.
