Formcalc - changing value of the text field

Hello,

please help me to solve this easy question.

I have 4 different fields with binding to the same element from interface, e.g. bindElement.

I need to hide these fields in case bindElement = Null and change values in case bindElement <> Null.

I'm using Formcalc:

For field 1:

if(HasValue($) == 0)

then $.presence = "hidden"

else

$.rawValue = "Field1"

endif

For field 2 (it should display value of bindElement):

if(HasValue($) == 0)

then $.presence = "hidden"

endif

For field 3:

if(HasValue($) == 0)

then $.presence = "hidden"

else

$.rawValue = "Field3"

endif

Now if I' changing Field 1, all fields getting value "Field1". And its wrong. Can I use rawValue or do I need another command?

Thanks!
