Er...did that solve it? Or do you also need to sort by the time (seems reasonable to me < s >). If so, then I was going to suggest a change:

=adir(thisform.x )
FOR ni = 1 to alen(thisform.x,1)
	thisform.x[ni,4] = dtos(thisform.x[ni,3]) + thisform.x[ni,4] 
NEXT
asort(thisform.x,4,-1,1)
this.rowsourcetype = 5
this.rowsource = "thisform.x"
this.requery()
