HI @NPatel12498 ,
How are the values in the gallery saved to the collection? Having had a better look at your screenshots, it seems you're trying to patch an empty collection to the data source: there's nothing in colMealDetails.
If you haven't done so already, set the OnChange property of the input controls in the gallery to something like the below:
Patch(
ColMealDetails,
ThisItem,
{
TitleID: ThisItem.TitleID.Text,
EventDate: Text(ThisItem.Evendate.SelectedDate),
RequiredMeals: Concat(ThisItem.ComboBox.SelectedItems, Value, ", "),
EventDuration: ThisItem.EventDuration.Text,
***Attendees: ThisItem.***Attendees.Text,
Non***Attendees: ThisItem.Non***Attendees.Text
}
)
This should properly populate the collection.
To then submit the collection to the DataSource, you can leave out the .Text, i.e.:
TitleID: ThisRecord.TitleID,
EventDate: ThisRecord.EventDate,
etc. etc.
The above works on the assumption that all columns are text types. In case you have other types as well, please share which columns have which types.
