Selecting a Row from List View throws an error

Hi,

 

I have a list view that pulls records from a Database, and that works.

 

I want to select a row and pass the record Name, Number and Date to three Text Boxes.

 

With the code I have, I can do that just fine, but just once.  I select the customer from a listbox, then it displays that customer's records in a seperate listview. 

 

If there are no records, there is no problem.

If there is one record, there is no problem.

If there is more than one record, I can click on any record in the list, and it passes the Name, Number and Date to my textboxes, which is what I want.

 

But, here is the problem, if I select a second record then it throws this error:

 

 

This is my code which retrieves the records from my database and populates listView1 (this works just fine):

Now this is the code that works just fine once, but crashes with the above error if I select a second record:

Any suggestions would be appreciated, 

 

Thank you!
