Adding previously selected items from listbox for a total?

I'm doing this program for a class; I have a listbox with values from 0-10 which are 'scores' which get recorded every time the user selects a new score (and clicks the button of course). I need to do the following;

  1. an average of the scores, which I get through an accumulator and the counter
  2. a number of scores, which I get through a counter

  3. get the total scores (this is what's giving me trouble)

    here's the code I have for this so far :

    intScore = Convert.ToDecimal(lstScores.SelectedItem)

'the counter and accumulator
intTotal = intTotal + 1 
decScoreAccumulator += intScore

' here's what calculates the average
If intScore > 0 Then
    decScorAvg = decScoreAccumulator / intTotal
End If

    Here's an image of it : https://i.sstatic.net/aomQO.png

The number and average I can get to work, since its just using the accumulator and the counter. But no matter what I do, I can't add the values selected for the total. So does anyone know how I can get it to give me total of all the selected scores?

You're code looks good, and you look like your doing everything correctly. You even already have the total in your current code:

decScoreAccumulator += intScore

Because you're adding the score each time to decScoreAccumulator, this variable has the total you're looking for (assuming it's not confined to the scope of the button click). HTH. Good luck!
