[Tkinter] Anyone know what happened to my button?

Try this, I can't test it so fingers crossed, I don't know if data.split(",") will be in the right order for self.form_frame.set_str_variables

OMG Yoriz, Its is working. Only thing it is the name of the labels because all say "Fecha de medicion" and look into the code and the names it is alright.

for row_index, text in (
            (1, 'Fecha de medición : '), (2, 'Hora de medición : '),
            (4, 'Voltage de Panel 1 : '), (5, 'Voltage de Panel 2 : '),

            label = tk.Label(self, text="Fecha de medición : ")
