Hi,

you have to use this script in the exit-event from the user input-date-field. This script is correct for a subtraction. (without error messages )

if(this.rawValue != null)

{

    var sDate = util.scand("yyyy-mm-dd", this.rawValue);

    //THE SEVEN IN THE END OF THE LINE YOU CAN CHANGE WHEN YOU WISH TO ADD MORE OR LESS DAYS

    var NewsDate = Number(sDate) - (24*60*60*1000*7);

    var nDate = util.printd("dd.mm.yyyy", new Date(NewsDate));

   //DatumsUhrzeitfeld2 --> YOUR TARGET FIELD --> PLEASE CHANGE THE NAME IN YOURS

    DatumsUhrzeitfeld2.rawValue = nDate;

}

I hope it's helpful for you?

Kind regards

Mandy
