Not being able to set a block at clicked block's location

So i don't know why but you can't set a block at the clicked block's location, idk if im doing it wrong because there is no errors.

on right click on a stone button:
    set {_button1} to location 1 meter west clicked block
    set {_button2} to location at clicked block
    set block at {_button1} to stone
    set block at {_button2} to red concrete

I tested your code and it works fine for me 2 blocks spawn next to each other you just need to place the stone button on the ground.
