So, I'm trying to create a list that pulls from a mysql database that displays an order # as a button and a new window expands to display the order numbers items/subitems with checkboxes to have checked when an item is selected. I have the window to pop up; however, nothing populates and my query prints out information/list. After all boxes are checked and a Finish button is clicked on, it will remove the order from the list to show it has been worked on. I found this on the forums; however, it's not pulling anything for me: How to fetch data from database and show in table in kivy+python
Thank you!
