Hey guys I've just started VB and we have a program to create.

So basically it is a very simple program. It records 3 stats from a soccer match (I've chosen goals, free kicks and fouls).
So we simply click the "add" button when a team has scored and the "minus" button to subtract if a mistake has been made,
anyway that's the simple stuff. I have created the very basic design which records the data and saves it when the save button is clicked.
However that data is only for 'one' match and we have to make a program that caters for 24 matches in total.

I have used a combobox so that I can easily choose which match we'll be adding the stats on.

What my program currently does:
-Choose which half
-Adds or subtracts a tally to a stat
-Save the stats
(However this is only for one match/round and we need 24 matches/rounds in total)



What I want to know:
-how to have a new screen each time a new round/match is chosen from the combobox but also saves the previous data
-save the data that is put into it so that the next time you choose/open the round/match the data will still be there (I know we have to use the streamwriter/streamreader thing)

This may seem complicated...well to me it is anyway, but I would really be thankful if someone could help me out.
