You need to get the index (instance number) of the row you are trying to
access.Try this on the layout:ready event of your sm field://get index
of current rowvar i = this.parent.index;//if current index is greater
than zero pull value from previous rowif (i > 0) { this.rawValue =
this.resolveNode("Row1[" + (i - 1) + "].em").rawValue;}
