Why can't get selected text in List?

[Sean]

   I used follow code to get selected text in List.
//MainCountryList items are:
//    China,England,France,Russian,American

// Main codes
Char      *label;
ListPtr   lstP;

lstP = (ListPtr) GetObjectPtr(MainCountryList); // MainCountryList
label = MemPtrNew(32);
if (label)
{
   StrCopy(label, LstGetSelectionText(lstP, LstGetSelection(lstP)));
   label = LstGetSelectionText(lstP, 2);

   // ControlValueAlert message's format is " ^1 is ^2"
   FrmCustomAlert(ControlValueAlert,"ListCountry", label, NULL);
   MemPtrFree(label);
}

// GetObjectPtr define
static void * GetObjectPtr(UInt16 objectID)
{
 FormPtr frmP;

 frmP = FrmGetActiveForm();
 return FrmGetObjectPtr(frmP, FrmGetObjectIndex(frmP, objectID));
}
// End main codes

   The app will open the alert window when I selected any item,
and the message is "ListCountry is xxx",but the "xxx" isn't any item's text
in MainCountryList,it's a random string.

   I think that is a point error! but I can't find where is error?

   Who can help me? Thanks!
