Form submit empty fields in SharePoint


I have a quick question. 

Actually when I submit my form, it save empty field in my SharePoint list. 

I just found that for a combobox I should use Update = combobox.Selected.fieldName.

Does someone knows how I should write this for a checkbox in a gallery and for a dropdown? 

Thnx in advance !

Hi @WarrenBelz

Thanks for your reply! I just tried some code but it doesn't seems to work. 


The code that I tried are as follow:


- Update = combobox.SelectedItem => No error but shows nothing in SharePoint

- Update = combobox.SelectedItems.Book => No error but shows nothing in SharePoint

- Update = combobox.Selected.Book => Error, book is underlined in Red



- Update = Gallery3.Selected =>No error but shows nothing in SharePoint

- Update = Gallery3.Selected.Value =>It's juste empty 


Am I doing something wrong? 

@mimii ,

What are the names and field types you are writing back to and if choice fields, are they single or multiple select.

Well, actually when an author is selected, the data are taken from the database and set into the fields and this works perfectly. 



- combobox

- single select 

- code that works: update = 



- is a checkbox into a gallery into a DataCard

- checkbox

- multiple select 

- code that doesn't work: update = Gallery.Selected.Value



- combobox 

- multiple select 

- code that doesn't work: update = comboboxBook.SelectedItems



- combobox

- single select 

- code that doesn't work = comboboxLanguage.Selected.language


All the update code are made on de DataCard level. 

@mimii ,

I was after the fields you are writing back to and what type they are.

Also Genre is a fairly complex workaround - are you sure you have followed the process correctly?
