Programming a button & list box

Question

I made a crucial mistake bt using the wrong format: Instead of using lstBill.Item.Text,Add ( "Receipt from Eddie's Equipment Rental") as part of the header,

 I wrote lstBill.Item.Text.Add(String.Format(fmtStr, "receipt from Eddie's Equipment Rental)). I ran the program before I could catch my mistake. What do I have to do to correct it. I have been able to add the correct format and cut the other, except the space is now unusable, and a message says that I am not able to make changes to a 64-bit application, and it is read-only.

Do I need to start all over again? Jeff Tatum.
