How do I use a table as a list for a dropdown in another table?

[thomx]

Hi, I have:

Table: Modes with the relevant columns

• Mode
• Server Time

Table: Event with the relevant columns:

• Mode

In my Table: Event, how do i use the contents of Table: Mode as dropdown options for my column Mode? I tried the basic functions but they keep me giving errors and I can't find the solution. Thanks.
