Hi @gjayne84,
Based on the needs you provided, I think the DateAdd function could achieve your needs.
I have made a test on my side, please take a try with the following workaround:
Set the DefaultDate property of the second DatePicker control to following:
DateAdd(DatePicker1.SelectedDate,30,Days)
On your side, you should set the DefaultDate proeprty of the DatePicker control within the Date 2 Data card to following:
DateAdd(DatePicker1.SelectedDate,30,Days)
More details about the DateAdd function, please check the following article:
DateAdd function
In addition, you could also consider take a try to set the OnChange property and OnSelect of the DatePicker control within the Date 1 Data card to following:
Set(PopulatedDate, DateAdd(DatePicker1.SelectedDate,30,Days))
Set the DefaultDate proeprty of the DatePicker control within the Date 2 Data card to following:
PopulatedDate
Best regards,
Kris
