Scripting How do u unref a ref you set using GetEquippedObject

[dedmax]

I have a spell set to reference the targets boots and replace them.

set Foot to Targetref.GetEquippedObject 5

targetref.removeitemns Foot 1

targetref.additemns Foot 1

targetref.Equipitemns Foot

If i use the same spell again on a new target and they are not

wearing boots the previous targets boots will get equipped.

How can i get the spell to forget the previous foot ref or reset

foot to be non referenced.
