Checkbox Value needs to Patch or UpdateIf to SharePoint List

[MarcBailey]

Originally - I thought this was going to be an easy one but I am still struggling with it.

I need some help on the approach and code for this.

I have a Gallery that has a Checkbox bound to each record.  I need to update my SharePoint List named ProjectSourceMatch with the value of the Checkbox using either Patch or UpdateIf.  I have tried using the OnCheck,OnUncheck, and OnSelect functions for the Checkbox with update code unsuccessfully.  I have also tried using a TextInput OnChange with code with Default set to: If(Checkbox3.Value=true,1,2) thinking that when the value changed it would trigger the OnChange function but it does not unless there is a manual entry into the TextInput (which is not an option).  I have attached an image of my test model.

Any help would be greatly appreciated - Thanks, Marc...

OnCheck:      Patch(YorDatabaseName, GalleryName.Selected, {Attendent: “Yes”})

OnUncheck:  Patch(YorDatabaseName, GalleryName.Selected, {Attendent: “No”})

Default:         If(ThisItem.ColumnNameLinkedToCeckBox="Yes",true,false)

Hey, this got me halfway. 

i have oncheck onuncheck and default setting like this and it works when i check the box.

But when i uncheck the box it displays  the right data change and uncheks the box for a few second, but returns to checked and also patches the data to "Yes" again.

any ideas would be appreciated.

Details:

Onedrive excel file

Using gallery and Toggle(Is there a difference using this and normal checkbox?)

Toggle: 

Oncheck: Patch(Attendees;ThisItem;{Arrival:"Yes"})

Onuncheck: Patch(Attendees;ThisItem;{Arrival:"No"})

Default: If(ThisItem.Arrival="Yes";true;false)

So everything works until u accidentaly check someone and want to uncheck
