HI,
Couple of things.
1. I don't see you patching Title. I do not know if for that list it is Required, I cannot see that property but double check and if it is just make it something simple
2. Your Name, you have Textinput1, now that is just the name of the a control, NOT an actual Value. But more importantly you set the Name as a Person or Group, which means you need to pass "Objects" of Type People or Groups. You are trying to pass a Control and that control is a TextInput which is not possible to pass as a Person.
3. For Home Office, you passed HomeOffice.Selected, not HomeOffice.Select.Value, which depends on the confuration of your choice.
So what I would ask and what I would do.
Fix #2, Name First as it's the most easily rectified. You have to have a Dropdown or ComboBox, where they can select 1-M People and then use the selected items (or selected item/Selected if you do not allow multiples being selected.
If that solves your problem great. If not then fix Title (if its required)
If that solves it great, if not, change the Choice to .Selected.Value (it should just be .Selected but again I cannot see everything)
