I am creating a multi-page data entry form with tkinter". It contains "next" and " back" buttons. The first page has few entry boxes for the users and the second page has some too. Is there a way I can get the value (entered by the users on the first page) displayed in the entry box if I went back to the first page from the second page to edit the values? Please let me know if this doesn't make sense.

I need to pass an entry from child form to a combobox on the parent. Any tips? I have been searching for help on this for months and cannot update the combobox to reflect the new data.
