While I'm figuring this needs to be addressed via my
scripting language wanted to ask here.  

Customers will buy a block of time to use my service. 
Time meaning "number of days".  90, 45, 60, etc.

Here are the fields relevant to this question:
PostStart [Date]
LenChoice [int]
DaysLeft  [int]

When they register , the current date is input
automagically into PostStart.  LenChoice is chosen by
the user and is the length of days they want this
block.  DaysLeft is where the calculation would be
done to hold the difference between the current date,
date posted and how many days were paid for.  This is
where I'm not entirely sure what to do.  I'm probably
inhaling gasoline or something but how would I get the
field to the numbers of DaysLeft ?

i.e. DaysLeft[today]= 3, DaysLeft[tomorrow]=2..etc

Thank you ,
Stuart

p.s. I'm on 4.0.22 , so no stored procedures.
