NPC Help plz

[Serenity]

hi all i have recently made a delvl script the delvls go from 1 to 7 as it stands..
The problem i am having the players are able to choose each delvl in any order...
i need it to check the delvl at each time so if they have not done delvl1 they cant do delvl2...

ive made a savevalue in every delvl #ACT from 1 to 7
How do i tell the system to check each txt file?

(EXAMPLE)

[@1]
#IF
CHECKLEVEL 40000
#ACT
SaveValue "QuestDiary\DelvlCheck\Delvl1.txt" Main %USERNAME
EVENTMSG [GROBAL] "Congratulations <$USERNAME> just deleveled.." 159
HLSCRIPTCMD CHANGELEVEL - 10000
GIVE LegendRing 1
#SAY
Thanks for doing Delvl here is your LegendRing..\
#ELSESAY
You are not yet level 40k - go level noob..

[@2]
#IF
CHECKLEVEL 40000
CHECK "QuestDiary\DelvlCheck\Delvl1.txt" Main %USERNAME
#ACT
EVENTMSG [GROBAL] "Congratulations <$USERNAME> just done there second delvl.." 159
HLSCRIPTCMD CHANGELEVEL - 12000
GIVE LegendBracelet 1
SaveValue "QuestDiary\DelvlCheck\Delvl2.txt" Main %USERNAME
#SAY
Thanks for doing Delvl here is your LegendBrace..\
#ELSESAY
