Formula :
Set(VarBarcode; Concat(BarcodeReader1.Barcodes; Text(ThisRecord.Value); ";"))
but i got some issue : 

1. The 'Concat' function has some invalid arguments.
 
2. Invalid argument type.
 
3. The 'Text' function has some invalid arguments.
 
4. Invalid name. 'ThisRecord' is not recognized.
 
5. The '.' operator cannot be used on Error values.

    Hey, I had the same issue with the barcodeReader, this is due to the last update of Power Apps that was automatically update on my Application. The barcodeReader no longer return a table.

    To resolve this I just had to change the version of power apps to : 3.25021.9

    I think all the version like 3.25022.8 or upper have the same issue.
     
    If you have the same just change manually the version here :
