What would the Return Node Output be for an Image?

So I have a function that determines what an image will be, either an attack icon or defense icon, but I need an output for it and I’m actually not sure what it should be.

As is, it returns an error stating “Binding: Property ’ /Script/UMG.Image:BrushDelegate ’ on Widget ’ DamageDefenseIcon ': Member:DamageDefenseIconFunction Has the wrong number of arguments, it needs to return 1 value and take no parameters.”
