I have the entire layout done, I just need a great deal of help in making my coding correct so I can make it run properly. I have included all the steps needed in order to complete it and want to make sure I'm headed in somewhat of the right direction but I am struggling greatly. Any help would much appreciated.

Design and code a project to calcu¬late the amount due for rentals.
Movies may be in VCR (videotape) format or DVD format
Videotapes rent for $1.80 each and DVD’s rent for $2.50.
New releases are $3 for DVD and $2 for videotape.

On the form include a text box to input the movie title and option buttons to indicate whether the movie is in DVD or a videotape format.
Use one check box to indicate whether the person is a member; members receive a 10 percent discount.
Another check box indicates a new release.
Use command buttons for Calculate, Clear for Next Item, Order Complete, Summary, and Exit.
The Calculate button should display the item amount and add to the subtotal.
The Clear for Next Item clears the check box for new releases, the movie title, and the option buttons
The member check box cannot be changed until the cur¬rent order is complete.
Include validation to check for missing data.
If the user clicks on the Calculate button without first entering the movie title and selecting the movie format, display a message box.

The Order Complete button clears the controls on the form for a new customer. Make sure to add to the customer count and rental sum for each customer order.
The Summary button displays the number of cus¬tomers and the sum of the rental amounts in a message box.
