Show_if when a column is a ref column

[Ann_Gish]

I have a column that is a ref column (Equipment) but I only want it to show if a certain choice is made from another column (Incident)

So I want the Equipment column to show if a certain choice is made from the Incident Column. Is this possible?

I’ve attached a screenshot.

I want the Equipment column to be shown if the “Equipment-lost” selection is chosen from the Incident list
