Calculate Difference in Days Between two Dates

Hi,

I'm trying to figure out how to calculate the difference in days between two dates using JavaScript in LiveCycle. (JavaScript knowledge = minimal)

Where "Start_Date" and "Current_Date" are the names of the two dates in the Hierarchy palette. (both Date/Time Field)

*Current date is using the Object > Value > Runtime Property > Current Date/Time

I need a Text or Numeric field displaying the difference in days. (Difference_in_Days)

I've noticed the following code being pretty standard amongst other responses:

var

Start_Date =new Date(Start_Date);

var

Current_Date =new Date(Current_Date);

var

nAgeMilliseconds = Current_Date.getTime() - Start_Date.getTime();

var

nMilliSecondsPerYear = 365 * 24 * 60 * 60 * 1000;

I know there's code missing, and the above code might not be correct.

Please advise.
