RE: problem with fields

[Robert McKenzie]

FldGetTextHandle takes a field pointer as its argument.  I would suggest that the 
field pointer you are passing in is most likely NULL or has become invalid.  It can 
become invalid if you add other objects to the field between the time that you get the 
field pointer and the time that you use it.  Safest code looks something like this:

{
  FormPtr  frm = FrmGetActiveForm();
  UInt16  index = FrmGetObjectIndex(frm, yourFieldIdHere);
  FieldPtr fld = FrmGetObjectPtr(frm, index);
  MemHandle hText = NULL;

  if (fld != NULL) { hText = FldGetTextHandle(fld); }
  if (hText != NULL) { /* do your stuff here */ }
}

Maybe the pointer to give to the function isn't one of FieldType or it 
isn't on the open forms?
