PowerApps Barcode Reader - Help needed with OnScan parameter

Hi,

I need some help with OnScan formula in PowerApps.

I currently patch data to excel web worksheet. User selects from dropdown, then inputs Order number. This works fine:

If(
!IsBlank(TextInput1.Text) && !IsBlank(Dropdown1.Selected.Workstations),
If(
IsBlank(LookUp(data, ORDER = TextInput1.Text)),
Patch(
data,
Defaults(data),
{
ORDER: TextInput1.Text,
TRACKAREA: Dropdown1.Selected.Workstations,
'TRACK-DATE': Text(Now(), "dd/mm/yyyy"),
'TRACK-TIME': Text(Now(), "HH:mm")
}
),
Patch(
data,
LookUp(data, ORDER = TextInput1.Text),
{
TRACKAREA: Dropdown1.Selected.Workstations,
'TRACK-DATE': Text(Now(), "dd/mm/yyyy"),
'TRACK-TIME': Text(Now(), "HH:mm")
}
)
)
);

Reset(TextInput1);
UpdateContext({ localConfirmationNotice: true });
SetFocus(TextInput1);
Refresh(data);

----------------------------------------------------------------------
Now I want to add the new BarcodeReader function. So user selects from dropdown, clicks on BarcodeReader button, and scans the "Order Number" and this patches the data to excel table.

Please advise where I am going wrong in following OnScan formula:

If(
!IsBlank(TextInput1.Text) && !IsBlank(Dropdown1.Selected.Workstations),
If(
IsBlank(LookUp(data, ORDER = First(BarcodeReader1.Barcodes).Value)),
Patch(
data,
Defaults(data),
{
ORDER: First(BarcodeReader1.Barcodes).Value,
TRACKAREA: Dropdown1.Selected.Workstations,
'TRACK-DATE': Text(Now(), "dd/mm/yyyy"),
'TRACK-TIME': Text(Now(), "HH:mm")
}
),
Patch(
data,
LookUp(data, ORDER = First(BarcodeReader1.Barcodes).Value),
{
TRACKAREA: Dropdown1.Selected.Workstations,
'TRACK-DATE': Text(Now(), "dd/mm/yyyy"),
'TRACK-TIME': Text(Now(), "HH:mm")
}
)
)
);

Reset(TextInput1);
UpdateContext({ localConfirmationNotice: true });
SetFocus(TextInput1);
Refresh(data);
