Change set on press key

[Catar]

Here it's not changing the set, just appears the messages "equip death set" and "equip haste set", but not equipping the items in inventory.

If you copied macro and all variables and set their ID correctly and have items in your opened backpack it should work like I showed on video.

And could you help me if I want to add more sets? changing it at + and - key?
I apologize for the inconvenience, I would like to add a set of physical damage and maybe others for UE's.

It should be easy
