Hi @Sophiegong

Unlock Your DataCard and click the text box with the value. You looking to Format this control. There should be Default Property and inside expression Parent.Default.

You need to wrap it in Text() Function now for date:

Text(Parent.Default,"dd-mm-yyyy")

I hope You mean 0.07 should be 0.07% but if You need to show 7% You need to multiple it by 100 and format it to % as below but if it should be 0.07% remove the 100 multiplayer and additional brackets

Text((Parent.Default)*100,"0%")

Hope this helps

It is really strange that the percentage is works, but date and number are not.

Text(DateTimeValue(Parent.Default),DateTimeFormat.ShortDate)
Finally I use this expression to get correct date format.

If(IsBlank(ThisItem.'Posting Date') || IsEmpty(ThisItem.'Posting Date'),IsBlank(),Text((ThisItem.'Posting Date'),ShortDate))

But You need to handle this on input if the error exist in the row isBlank() will not help
