When form is in New Mode then the Calculation works but Not when form is in Edit Mode?

[Lorem1960]

I have a form that allows users to enter expenses in Euro, the form also contains the current ExchangeRate, when a users enters the Amount in Euro, the Amount in USD is calculated based using the below formula that is placed in the Default Property of the Item

named AmountUSD.

Coalesce(Parent.Default,Text(With({AE:Value(DataCardValueAmountEuro.Text),ER:Value(DataCardValueExchRate.Text)},AE/ER),"###.00"))

This works just fine, however, when my form is in Edit mode and a user wants to update the Amount in Euro or Update the Exchange Rate, the AmountUSD does not get calculated?

So it seems that when the form is in Edit Mode the above formulate does not get triggered.

Anyone has any idea why this happens? Thanks!

Coalesce() will supply the first Nonblank value.  In your case, when the form is in edit mode, Parent.Default exists so processing stops as there is already a value.  If you change the order as below, then your formula should reflect the change.

Coalesce(Text(With({AE:Value(DataCardValueAmountEuro.Text),ER:Value(DataCardValueExchRate.Text)},AE/ER),"###.00"),Parent.Default)
