Hi All

I have a page (as opposed to a table) where I can scan or type in a reference in a field and find the record I am looking for. The field is called Scan and it is set a to be a Global variable in memory (browser).

This version doesn't find the record

let a := this;
let b := first(select StockByBin where Scan = a.Scan);

This version does find the record

let a := this.Scan;
let b := first(select StockByBin where Scan = a);

Any ideas why?

Regards John
