KOTH Skript Help!

[iChinchillinq]

So I've been testing out a King of The Hill Skript for a little while, and got it down to 2 errors, which I can't fix.

Variables:
    {skoth} = false
    {kmsg} = false
 
on walk on polished andesite:
    if {skoth} is true:
        if player's location is within 3 blocks of {koth}:
            if size of {capping::*} is 1:
                stop
            else:
                if size of {capping::*} is 0:
                    add player to {capping::*}
                    if {kmsg} is not true:
                        broadcast "&bVile &7» &c%player% &7is now capturing the KoTH! 30 Seconds Left!"
                        set {kmsg} to true
                        wait 15 seconds
                        if player is in {capping::*}:
                            broadcast "&bVile &7» &c%player% &7is capturing the KoTH! 15 Seconds Left!"
                            wait 15 seconds
                            if player is in {capping::*}:
                                broadcast "&bVile &7» &c%player% &7has captured the KoTH!"
                                execute console command "/cc give physical Enchanted 2 %player%"
                                set {skoth} to false
                                set {kmsg} to false
                                remove player from {capping::*}
 
on walk on grass:
    if {skoth} is true:
        if player is in {capping::*}:
            if player's location is not within 3 blocks of {koth}:
                if player's location is within 4 blocks of {koth}:
                    broadcast "&bVile &7» &c%player% &7is no longer capturing the KoTH!"
                    set {kmsg} to false
 
command /setkoth:
    permission: rank.admin
    permission message: &cInsufficient Permissions.
    trigger:
        set {koth} to player's location
        send "&aSuccess! &7&o(Set The KoTH's Location to %player's location%!)"
      
command /startkoth:
    permission: rank.admin
    permission message: &cInsufficient Permissions.
    trigger:
        set {skoth} to true
        broadcast "&bVile &7» A KoTH has begun at &c%{koth}%&b!"
 
command /endkoth:
    permission: rank.admin
    permission message: &cInsufficient Permissions.
    trigger:
        set {skoth} to false
        set {kmsg} to false
        delete {capping::*}
        broadcast "&bVile &7» The KoTH was abruptly ended!"
      
command /koth:
    trigger:
        send "&bVile &7» The KoTH's location is &c%{koth}%&7!"

Here are my errors: http://prntscr.com/jgp21j
