Lua Quest Log & Storage Value

[TiuTalk]

Hi there...

Can someone explain me how these <missionstate id="5" and these startvalue="4" endvalue="6" work?

<?xml version="1.0" encoding="UTF-8"?>
<quests>
    <quest name="Example Quest I" startstorageid="30031" startstoragevalue="1">
        <mission name="The head of Kiper" storageid="1001" startvalue="1" endvalue="3">
            <missionstate id="1" description="Kill Kiper!"/>
            <missionstate id="2" description="Give his head to Talaturen!"/>
            <missionstate id="3" description="Take the medal you got from Talaturen to Ruly!"/>
        </mission>
        <mission name="Ruly's Revenge" storageid="30031" startvalue="4" endvalue="6">
            <missionstate id="4" description="You received a document with instructions from Ruly, follow them."/>
            <missionstate id="5" description="Go back to Ruly and tell him that you followed his instructions to the end."/>
            <missionstate id="6" description="You got a reward from Ruly, he was very thankful with that you helped him to take his revenge."/>
        </mission>
    </quest>
