I'm trying to make a schedule. Here, with the data I received by entry, the mineral selected in the optionmenu will be taken and compared with the values in the database, but the button function does not work exactly. The error it gives is: Typeerror: buttonfunction() missing 2 required positional arguments: 'variable' and 'entryvalue'. I couldn't figure out how to take the values into the function, and the other function doesn't give the program the value it assigns to the variable variable. I don't know how much I was able to tell, but I would appreciate it if you could help. https://www.technopat.net/sosyal/konu/python-kodundaki-hata-nedir.1994095/

Well, your code works, but it was terribly formatted, and there are dots at the end of the lines that shouldn't be there.

Here - fixed it for ya.

you dont have given the paramters for button function. you can give the paramteres.you can edit and use this code;

submit_button = Button(root, text="Submit", font=("Calibri", 10), command= lambda: buttonfunction(variable, entryvalue))
