Trying to make skill point redeem thing {HELP}

[OneMore]

command /redeem [<text>]:
    permission: redeem.player
    trigger:
        if arg-1 is "speed":
            if {skillpoints::%uuid of player%} >= 1:
                set {speed::%uuid of player%} to the player's walk speed
                add 0.1 to {speed::%uuid of player%}
                send "&aYour speed has been slightly increased!" to player
                broadcast "%{speed::%uuid of player%}%"
                remove 1 from {skillpoints::%uuid of player%}

So, I am trying to make it so if a player types /redeem speed (and they have 1 skill point) their speed will be increased by 0.1. I tried this code, but even when I try it everything works, execpt the speed stays the same. When I broadcast the variable, it's always "0.3" as the player's speed. If anyone knows how to fix this, please tell me! Thanks in advance.

since youre not actually changing the player's walk speed (youre only increasing the variable) , each time you run your command youre just setting {speed::%uuid of player%} back to 0.2 (the default player walk speed) and then adding 0.1 to it, resulting in the variable being 0.3 every time.

so to fix this you just need to actually change the player's walk speed like so:

set player's walk speed to {speed::%uuid of player%} #put this after line 7
