Solve the following python programming problem given the following code:
def __init__(self, parent = None, prefix = None, det_type = 'ME-4', is_xsp3 = False, nmca = 4, title = 'Select Epics MCA Detector') : 
    if (prefix is None) : 
        prefix = self.def_prefix 
if (det_type not in self.det_types) : 
        det_type = self.det_types [0] 
wx.Dialog.__init__ (self, parent, wx.ID_ANY, title = title) 
    self.SetBackgroundColour ((240, 240, 230)) 
    self.SetFont (Font (9)) 
    if (parent is not None) : 
        self.SetFont (parent.GetFont ()) 
self.is_xsp3 = Check (self, size = (120, (- 1)), default = False) 
    self.dettype = Choice (self, size = (120, (- 1)), choices = self.det_types) 
    self.dettype.SetStringSelection (det_type) 
    self.prefix = wx.TextCtrl (self, (- 1), prefix, size = (120, (- 1))) 
    self.nelem = FloatCtrl (self, value = nmca, precision = 0, minval = 1, size = (120, (- 1))) 
    btnsizer = wx.StdDialogButtonSizer () 
    if (wx.Platform != '__WXMSW__') : 
        btn = wx.ContextHelpButton (self) 
        btnsizer.AddButton (btn) 
btn = wx.Button (self, wx.ID_OK) 
    btn.SetHelpText ('Use this detector') 
    btn.SetDefault () 
    btnsizer.AddButton (btn) 
    btn = wx.Button (self, wx.ID_CANCEL) 
    btnsizer.AddButton (btn) 
    btnsizer.Realize () 
    hline = wx.StaticLine (self, size = (225, 3), style = wx.LI_HORIZONTAL) 
    sty = (LEFT | wx.ALIGN_CENTER_VERTICAL) 
    sizer = wx.GridBagSizer (5, 2) 
    def txt(label) : 
        return SimpleText (self, label, size = (120, (- 1)), style = LEFT) 
sizer.Add (txt ('  Detector Type'), (0, 0), (1, 1), sty, 2) 
    sizer.Add (txt ('  Uses Xspress3?'), (1, 0), (1, 1), sty, 2) 
    sizer.Add (txt ('  Epics Prefix'), (2, 0), (1, 1), sty, 2) 
    sizer.Add (txt ('  # Elements'), (3, 0), (1, 1), sty, 2) 
    sizer.Add (sty.dettype, (0, 1), (1, 1), sty, 2) 
    sizer.Add (self.is_xsp3, (1, 1), (1, 1), sty, 2) 
    sizer.Add (self.prefix, (2, 1), (1, 1), sty, 2) 
    sizer.Add (self.nelem, (3, 1), (1, 1), sty, 2) 
    sizer.Add (hline, (4, 0), (1, 2), sty, 2) 
    sizer.Add (btnsizer, (5, 0), (1,...

    
    

    Fix the buggy line: sizer.Add (sty.dettype, (0, 1), (1, 1), sty, 2)

#Here is Python program to fix the buggy line: sizer.
