My python program dont save in excel file

My python program only saves the first row but doesn't save the other columns. On my Track.xlsx file when I press the save button, the program only saves the first line the rest does not save it and it is as if it did not take into consideration the text inside the various textboxes and comboboxes.

I am a beginner, can anyone help me?
