Changing runspeed in my mod

[notsaying]

Hey I got a problem with my mod I tried to change my character's running speed each time a new day rises and I copied the "inst.components.locomotor.runspeed" so there won't be problems of typing or something and it just crashed when a new day started and told that "locomotor" is a nil value. Can someone help? here's the entire code of this part:

inst:ListenForEvent( "daycomplete", function(inst, data)
    
    inst.components.locomotor.runspeed = 10
    
    FireStat(inst)
    
    local DailyRandomElement = math.random(1,8)
    if DailyRandomElement == 1 then
        GetPlayer().components.talker:Say(GetString(GetPlayer().prefab, "ANNOUNCE_DEERCLOPS"))
        FireStat(inst)
    elseif DailyRandomElement == 2 then
        GetPlayer().components.talker:Say(GetString(GetPlayer().prefab, "ANNOUNCE_BOOMERANG"))
        WaterStat(inst)
    elseif DailyRandomElement == 3 then
        GetPlayer().components.talker:Say(GetString(GetPlayer().prefab, "DESCRIBE.YELLOWSTAFF"))
        WoodStat(inst)
    elseif DailyRandomElement == 4 then
        GetPlayer().components.talker:Say(GetString(GetPlayer().prefab, "DESCRIBE.MAXWELL"))
        MetalStat(inst)
    elseif DailyRandomElement == 5 then
        GetPlayer().components.talker:Say(GetString(GetPlayer().prefab, "DESCRIBE.RED_CAP"))
        EarthStat(inst)
    else
        GetPlayer().components.talker:Say(GetString(GetPlayer().prefab, "ANNOUNCE_CHARLIE"))
        NormalStat(inst)
    end 
    end, GetWorld())

**Normally it should have a 12.5% chance of changing the running speed, but it doesn't work anyway. I really need help.
