how can we write expression for checking if single control value is null or not, if it is not null it should return some value and if it is null then it should return some different value.
And I want to write this in some expression.

hello @suvarnap, great question!!
where is the control value coming from (barcode scanner, Input Widget, etc.)?? once you store it in a Variable, you can use logic this to do what you’re describing:
let me know if you have further questions!!
