Alright folks...I'm new to this visual basic stuff, and to the site. I am working on an assignment for a class...it'll probably look pretty easy to the rest of you, but I just can't figure it out.
What I need to do is take the information from the input box, the 'quiz scores' that are entered and put them in the list box. The way it is set up now, as you'll see is that it takes the last score and enters it all 5 times. It appears that all of my other calculations work. I'm not looking for someone to completely write the code for me, as I really need to and want to learn this...but maybe just a little 'shove' in the right direction?!
Below is all of the code I have so far: I changed the part I need help with to red font so you can find it quicker...Thanks!!!!!
' Project: IT Department Grades
' Purpose: Allows the user to enter 5 scores, they will be displayed in a list box
' and then can be used to calculate the average and a grade letter will
' be displayed.
