Hi
I've searched and found some similar issues on the form/card for changing a value based on another but i can't get mine working. Im wondering if its to do with that im using dates?
I have a DataValue in my card with requires a submission date to be selected

Based on that selected value, i need my other date to auto add 7 days (or 5 working days) as default

I've tried the OnChange and the OnSubmit with the following formula but it doesnt work:
DataValueSLA.SelectedDate = DateAdd(DataValueSubmittedDate.SelectedDate,7,Days)
The formula returns not errors but i dont get the results i require. Ideally everytime the SubmittedDate is changed, i need the SLA date to auto adjust by the 5 working days (7 days)
