pass parm to ui-field

I am passing “Member_Id_CR_Open={{{$}}}&ViewCR=Member” in an include field.  I want to use {{$Param.ViewCR}} to create a UI-Field.

I have tried creating a formula {{$Param.ViewCR}} but it shows nothing.  How do I use a parm in a UI-Field?


Just make your ui-only field a text field, then set a url/param condition for it in your model definition.
