Fields do not move up when its preceding field is blank.

Hi,

I have a  "positioned" subform to display Address.  This Address is of 3 lines one below the other ( in the center of the page).

                     Line1

                     Line2

                     Line3

This entire subform is embedded in a "flowed" subform.

Line 2 will be blank in most of the cases. If Line 2 is blank, I need to move Line 3 up. I have a code in place for Line2 shown below.

if (this.rawValue == null || this.rawValue == ''){

     this.presence = "hidden";

}

But this does'nt move the Line 3 up.  I don't see any other options to make this work.

Appreciate help on this.

Thanks,

Pavan
