I have this gallery which contain items that were already created inside SharePoint, and i want to loop through them and update the items, when clicking on the Submit button:-


I tried the below formula inside the submit button, but the issue is that all the items will get the last gallery's item values, so in the above example all items will have Quantity = 300 and Quantity Each Network = 500, and so on:-
Patch('Printing Orders Details',
ForAll(PrintOrderDetailsGallery.AllItems,
{ ID: ID,
Quantity: Value(PrintOrderQuantity.Text),
'Quantity Each Artwork':PrintOrderQuantityForEachartwork.Text,
'Network ID':PrintOrderNetworkComboBox.Selected.ID
}
)
)
and advice?
