I need my program to output and input a customer ID and sales amount multiple times. I need it to display both outputs, customer ID and sales amount, on mulltiple lines. It also will need to accumulate the sales amount and then display the total sales. it should look something like that.[code...]
I think that I was supposed to use a messagebox but wrote the program a different way. the form.vb was already locked, but I added two text boxs. Not sure if I did this right because I need to enter multiple sales for one customer ID.[code...]
