"HELP ME" Correct way using IsStarting() function

[virginharvester]

i am novice at creation kit, and this is my first mod using creation kit

i like to try IsStarting() function, i have read it in :

http://www.creationkit.com/fallout4/index.php?title=IsStarting_-_Quest

if (MainQuestProperty.IsStarting())  Debug.Trace("The main quest is still starting")endIf

so i create new misc quest, put new quest stage

at stage 10 Papyrus :

 

if (min01.IsStarting())

Debug.Trace("The Quest has started")

else
Debug.Trace("The Quest not Started")

endif

 

and i compile , the result is "Min01 is undefined"

where part i am wrong?

can somebody type correct that syntax?
