im trying to write a script where if a persons joining date is 2/18/2011, six months later they start accuring 1 vacation day each month. So far this is what i got:

 

dateDiff = input.Date_of_Joing - zoho.currentdate;

If (dateDiff < 180 (refering to days)

      Number_of_Days_Available = 0

else

      Number_of_Days_Available =

 

I dont know what to put after that
