hi @Larussa Ok.
On the scan button add the following code
//Lets get the data from the scanner, you will have Set(_Scanned,BarcodeSanner1.Value)
Set(_Scanned,"R1,R2,R3,R4,R5,R6,R7,R8,R9,R10,R11,R12,R13,R14");
//lets split the barcode string so we can assign it to the datacards
ClearCollect(_ScannedArray,ForAll(Split(_Scanned,","),{Scanned: Result}))

Above unlock the datacard above and set the default of the card as
col1 default = First(_ScannedArray).Scanned
Col2 = Last(FirstN(_ScannedArray,2)).Scanned
Col3 = Last(FirstN(_ScannedArray,3)).Scanned
Col4 = Last(FirstN(_ScannedArray,4)).Scanned
Col5 = Last(FirstN(_ScannedArray,5)).Scanned
Col6 = Last(_ScannedArray).Scanned
On the Save button OnClick = SubmitForm(YourForm);
NewForm(YourForm)
In SharePoint

That should do it for you
