The parameter name is incorrect (as was already pointed out), but you
also need a use clause:

  TT : Translation_Tables.Container_Type;
  use Translation_Tables;
...
  Insert (TT, "key", To_Container ("value"));

If you're manipulating string containers (Charles.Strings.Unbounded,
etc), then it may be easier to define a conversion operator:

  function "+" (S : String) 
    return Charles.Strings.Unbounded.Container_Type
    renames To_Container;

This allows you to say:

  Insert (TT, "key", +"value");

In C++, the string ctor allows type conversions be made silently (i.e.
there is no syntactic penalty), but Ada requires type conversions to
be explicit.
