I am a beginner at Visual Basic, and my teacher wants a multidimensional code that will cause this spa service price to come up with those values. How could I make the array work, and have the currency to come up in the ServicePriceTextBox?

That if statement is one long complicated mess. Try simplifying it by putting ifs inside of other ifs and then once you get to the point where you have valid data, then you can use the values to select the correct value and display the price.

For instance...

If SpaServiceComboBox.Text <> "" And RoomNumberListBox.SelectedIndex <> -1 then
      Dim Room as Integer = RoomNumberListBox.SelectedIndex

      If OneFourthHourRadioButton.Checked then
           ServicePriceTextBox.Text = ArrayInteger(Room,0)   
      ElseIf HalfHourRadioButton.Checked then
           ServicePriceTextBox.Text = ArrayInteger(Room,1)
      ElseIf ThreeFourthRadioButton.Checked then
           ServicePriceTextBox.Text = ArrayInteger(Room,2)
      ElseIf HourRadioButton.Checked then
           ServicePriceTextBox.Text = ArrayInteger(Room,3)
      ElseIf HourAndHalfRadioButton.Checked then
           ServicePriceTextBox.Text = ArrayInteger(Room,4)
      Else
           ServicePriceTextBox.Text = "Ask Receiptionist About Pricing"
      End If
End If

The above code is an example. But here we have taken the room number and checked which radio button has been selected. Based on those two pieces of info, we look up the price from ArrayInteger and put the price into our Textbox.

Things to take away from this is that we don't have to test the same thing multiple times (Why check if the spa service combo text is not null each time? test it once and if it passes, continue on with other checks.

That helped a lot actually. My teacher is just huge on spreading the code out, but doesn't explain how to simplify it as much. Thanks for explaining it along with the code. Now, I have another one that is getting me all sorts of confused. I'll probably post again soon, but don't know how to as much.
