Date Range Reveal

I just made that assumption to keep the code cleaner, the dates could be either way round would just need to code to allow for a possible negative value. if you have a negative value the the "if ( dateChange > millisec3Days )" wouldn't catch the 3 days elapsed days correctly.

Is there any requirement that date 1 must be before date 2?

Do you want the validation to be performed as the user enter the dates into each field or by using a button.?

HI,

Something like the following should help

var curDoc = app.doc

var date1 = curDoc.getField("Date_Field_1");

var date2 = curDoc.getField("Date_Field_2");

// make them into dates, so we can do date maths on them - the field returns a string.

var actualDate1 = new Date ( date1.value);

var actualDate2 = new Date ( date2.value);

// this assumes date 2 is in the future, if it is the other way round you may need to change this line.

var dateChange = actualDate2 - actualDate1;

var millisec3Days = 259200000

// compare to 3 days

if ( dateChange >  millisec3Days )

{

    curDoc.getField ("Text4").hidden = false;

}

else

{

    curDoc.getField ("Text4").hidden = true;

}
