Problem appears when trying to add a new code.

Hi,
I was trying to add a new code yesterday, then I have run the program and tested it out.
But when I reach the last record, I am getting this error message (see the image below).
Can you identify what the problem possibly could be?
I’m unable to troubleshoot it.

This method should only be called on ResultSet objects that are scrollable (type TYPE_SCROLL_INSENSITIVE).
