Programming in Visual Basic 2010 Can someone help me with chapter 3 vb mail order code?

The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours).

The screen will allow the user to enter the employees name, the total hours worked, and the amount of the stores total sales. The amount of sales needs to be entered only for the first employee. (Hint: Dont clear it.)

The Calculatebutton will determine the bonus earned by this employee, and the Clearbutton will clear only the name, hours worked, and bonus amount fields. A Printbutton allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.
