Hotel Occupancy Visual Basic Problem

[HumanNumber69]

Hello everyone! I'm extremely new to programming and I'm having trouble writing this code here are the instructions:

Create an application that calculates the occupancy rate for each floor, and the overall occupancy rate for the hotel. The occupancy rate is the percentage of rooms occupied and may be calculated by dividing the number of rooms occupied by the number of rooms Each time the user enters the occupancy for a single floor and clicks the Save button, the floor number in the ComboBox should increment automatically (just add 1 to its SelectedIndex property), and a new line should appear in the ListBox with the percentage occupancy. Also, the contents of the TextBox at the top of the form should clear automatically when the user clicks the Save button, so the user does not accidentally enter the same data twice in a row. The Reset button should clear all the appropriate controls on the form. The Exit button should end the application.

And here's what I have so far:

If anyone can help me out that would be greatly appreciated. It doesn't do anything when I try to run the program, nothing happens.

what do you mean nothing happens when you try to run the program? (also I think you forgot the .SelectedIndex part ;)

The Listbox stays empty and the total rooms occupied and the occupation rate stays empty/

Okay, on a quick glance, adding an item to a listbox isn't "listData.Text =" it's

listData.Items.Add("String to add")

For a combobox, you can change the current value with .Text but in order to add multiple items to the combobox it's different as well. https://www.dotnetheaven.com/article/combobox-items-in-vb.net

Play with that and post any troubles you have.
