Problem with insert in STL list

Hi!
This is the code that gives me problem

std::list<AnsiString> l_pPadres;//list with elements: "uno" "dos" "tres" "cuatro"
std::list<AnsiString> l_pHijos;//list with elements: "alfa" "beta" "delta"
//I wont insert all l_pHijos elments between elements  "dos" and "tres" of the list  l_pPadres
//Then the list l_Padres must be:: "uno" "dos" "alfa" "beta" "delta" "tres" "cuatro"

//1 step: I found where is "dos " in the list  l_pPadres
std::list<AnsiString>::iterator mi3Iterador;
for(mi3Iterador = l_pPadres.begin();mi3Iterador != l_pPadres.end();mi3Iterador++)
{//begin for mi3Iterador
if(*mi3Iterador) == AnsiString("dos"))
break;
}//end for mi3Iterador

//2 step: I put the pointer after "dos"
mi3Iterador++;

//3 step: I try to do the insertion
mi3Iterador.insert(mi3Iterador, l_pHijos.begin(), l_pHijos.end());

//4 ste: When I compiled I have the following message error:
list<AnsiString,allocator<AnsiString>>::iterator

Please, could anyone help me?
Regards
