Solve the following python programming problem given the following code:
def _replace_dialog(parent) : 
    root = Tk () 
    root.title ('Test ReplaceDialog') 
    (width, height, x, y) = list (map (int, re.split ('[x+]', parent.geometry ()))) 
    root.geometry (('+%d+%d' % (x, (height + 150)))) 
    def undo_block_start() : 
        pass 
def undo_block_stop() : 
        pass 
text = Text (root) 
    text.undo_block_start = undo_block_start 
    text.undo_block_stop = undo_block_stop 
    text.pack () 
    text.insert ('insert', ('This is a sample string.
' * 10)) 
    def show_replace() : 
        text.tag_add (SEL, '1.0', END) 
        replace (text) 
        text.tag_remove (SEL, '1.0', END) 
button = Button (root, text = 'Replace', command = show_replace) 
    button.pack () 

    
    

    Fix the buggy line: root.geometry (('+%d+%d' % (x, (height + 150))))
