actionscript 3 - Line 49, 52,55,58,61,64- 1119:Access of possibly undefined property text through a reference with static type String -

not sure doing wrong, removed text text box fields why still getting error ?

code below :

switch (day) {     case "sun":         day.text = "monday";     break;     case "mom":         day.text = "tuesday";     break;     case "tue":         day.text = "wednesday";     break;     case "wed":         day.text = "thursday";     break;     case "thu":         day.text = "friday";     break;     case "fri":         day.text = "saturday";     break;     case "sat":         day.text = "sunday";     break; }  switch (codetoday) {     case "0":     case "3200":          var weather00:weather00 = new weather00();         _weathertoday.addchild(weather00);         _weathertoday.scalex = 10.85;         _weathertoday.scaley = 158.75;         break;      case "1":     case "3200":          var weather01:weather01 = new weather01();         _weathertoday.addchild(weather01);         _weathertoday.scalex = 10.85;         _weathertoday.scaley = 158.75;         break;   } 

i suppose 'day' string variable , have not text property - here -> string
components have text property like: textfield , textarea
