I need help with the following

Visual Basic Script is Windows Forms App (.NET Framework 4.7.2)

Change the Do clause to use the While keyword rather than the Until keyword. If the counter contains the number 0, display a message informing the user that no sales amounts were entered. Display the message in a message box. After displaying the average sales amount, change the lblAvg controls BorderStyle property to BorderStyle.None, blink the text in the control five times, and then change the BorderStyle property back to BorderStyle.FixedSingle.
