Hi @jamescosten,
Do you want to populate the CurrentLocation field either with scanner value or "Booked Out"?
Could you please tell me the detailed condition to define which value will be populated?
I just assume that you will scan the location if you don't click the book out button, so you need to set a variable to save the barcode scanner value or book out value.
1). Set the OnScan property of the BarcodeScanner4_1 as below:
Set(var1,BarcodeScanner4_1.Value)
2). Set the OnSelect property of the Book Out button as below:
Set(var1,"Booked Out")​
3). Set the Default property as below:
var1
