I have been doing lots of searching to find the reason why all a sudden my form will not save. I found it could be a required field isn't being fulfilled, but i doubled checked and all my fields that are required are visible. the form worked before i updated one list items Display name and deleted another list item column and made a new person or group type column to replace it with same name, but made sure to have "allow multiple selections" selected. (i was getting the error " The property on this control expects Record value.." ). so it doesn't seem to make sense why it work now.
below is what the form looks like on Sharepoint and showing i have the default Item setting for the SharePointForm1.
