Loop not executing

[Freddols]

Hi there!

So i am trying to do the following loop, but it does not work...

every second:
    loop all entities in radius 12 around {PinkMushroom1}:
        apply regeneration to the loop-entity for 1 second

Now, i know you may say i have not set the Location Variable, but in fact i have set it earlier in the code with a command that looks like the following:

command /setmushroom <text> <number>:
    trigger:
        if arg 1 is "Pink":
            set {%arg 1%Mushroom%arg 2%} to player's location
            message "&dLocation Set!"
        if arg 1 is "Blue":
            set {%arg 1%Mushroom%arg 2%} to player's location
            message "&9Location Set!"

I have no idea to why this does not work, and would require some assistance... Thanks!
