Entering Comic Information
This is the first screen in a series of screens that lets you enter the comic book information.
On this screen you should enter information in all the fields except one. If you don't, it can hurt the database by corrupting the connections between the tables.
Cover Price is not as essential as the others and can be safely left blank. Cover date also will fill in a random value if its left blank and publisher will fill in Unknown. But neither is a preferred entry I would think.
Also, the Volume and Issue fields are number only fields. Don't add any letters to them because that will cause an error to occur. And to keep from breaking the number 0 will replace the entered values.
