Hi I'm new to InfoPath and hoping I might find help here. I have a form connecting to a SharePoint list. I have a Date Field called Collection Date which is set to Date only in SharePoint. I was trying to get the Date Picker control in InfoPath to default to yesterday. When I use addDays(today(), -1), I get the red dotted lines around the field if I try to submit the form. I also tried to concatenate T00:00:00+00 onto the date concat(addDays(today(), -1),"T00:00:00+00) but no joy with that either. I'd really appreciate some help with this. Thanks.
