Do you put directly to .value property ? and controlsource = "vitals.date" which is date type ? If rowsourcetype is set to fields than just seek() corresponding date, if not then put something like this in init :

for ix=1 to this.listcount
	if this.list(ix,2) = dtoc(yourdatevaluehere)
	  this.listindex = ix
	  exit
	endif
endfor
