Jill,
First add a form property "nActiveRow" to store the active record # in the grid. Be sure you initialize it to a number.

Second, in the form Init (or grid init)

THIS.SETALL("DYNAMICBACKCOLOR",;
   "IIF(recno() = thisform.nActiveRow, ;
   RGB(192,192,192),RGB(255,255,255))","column")

Next, update the nActiveRow value when you change rows in the grid. Put code in the AfterRowColChange method:

thisform.nRow = recno()
this.refresh
