Plugin Help Skript Help

Hello Bukkit community, I recently made this Skript, but for some reason it doesn't work. Whenever I try to load the Skript, it says "Indention error," although I'm pretty sure I have everything indented correctly. Any help would be amazing, as I'm new to Skript Also, I need this as fast as possible, as I'm hosting a somewhat big UHC filled with tons of YouTubers xd.

Code:

command /uhc [<text>]
    permission: skript.op
    trigger:
        if arg 1 is "start" or "go":
            command "/pvp global off"
            command "/freeze all"
            command "/mutechat"
            command "/broadcast &4MythUHC &8» &fUHC starting.."
            wait 3 second
            command "/broadcast &4MythUHC &8» &fLoading enabled scenarios."
            wait 3 second
            command "/broadcast &4MythUHC &8» &fKillboard enabled."
            wait 3 seconds
            command "/broadcast &4MythUHC &8» &fScattering teams."
            command "/sca world 1000 teams"
            wait 15 seconds
            command "/broadcast &cUse /help for mining rules!"
            wait 1 tick
            command "/broadcast &cUse /scenarios for enabled scenarios!"
            wait 3 seconds
            command "/broadcast &4MythUHC &8» &fThe game has started!"
            command "/freeze all"
            command "/mutechat"
            command "/worldborder set 100 3600"
            wait 10 minutes
            command "/feed all"
            command "/heal all"
            command "/broadcast &4MythUHC &8» &fFinal heal has been given."
            wait 10 minutes
            command "/pvp global on"
            command "/broadcast &4MythUHC &8» &fPVP has been enabled!"

Also, since Bukkit formats code weirdly, here is a Hastebin to the Skript:
