Carmen:

Try this code in the InteractiveChange event of the textbox. Change the Control names as appropriate:

IF !EMPTY(THIS.Value)
   WITH THIS.Parent.List1
   	FOR i = 1 TO .ListCount
      	IF UPPER(ALLT(THIS.Value)) = ;
           LEFT(UPPER(.ListItem(i)),LEN(ALLT(THIS.Value)))
         	.Selected(i)=.T.
	         EXIT
   	   ENDIF
	   ENDFOR
	ENDWITH
ENDIF
