question about a command (horse_appearance)

[Syriza 281]

hey guys,

I implemented the horse_appearence system but if I unsummon my horse the item stays in the slot, I've written a command to call back the horse and unequip the item, it works.

but if im riding the horse, it should say "You need to stop riding before unsummon"

 

So currently my problem is it unequips even if im riding the horse, this cause some bugs, thats why i dont want to unsummon the horse if player is riding
