GlideDateTime.subtract doesn't work

[abrouf]

I used the following commands on default value to calculate the number of days subtracting current date to due date but didn't work. Any comment or advise is greatly appreciated.

javascript:calendar_duration = GlideDateTime.subtract(due_date.getDisplayValue(), gs.nowDateTime());

Following this syntax:

<duration_field> = GlideDateTime.subtract(<start_field>.getDisplayValue(),gs.nowDateTime());

HI Rouf

You are missing object for the due date.

OBJECT.due_date.getDisplayValue()

if dueDate is a GlideDateTime, you just do the following:

GlideDateTime.subtract(due_date, gs.nowDateTime());

Try if this works:

Following this syntax:

<duration_field> = GlideDateTime.subtract(new GlideDateTime(current.due_date),gs.nowDateTime());
