With VGA UserEnd Schedule Editor, when "SetSign Time and Date" is clicked I get the error message:
"List index out of bounds (-1)"

What does this mean and how can I fix it? Thank you for your time!

This is a known issue with applications that appears when an internal module of the application is not working properly, or you entered wrong data and since the software doesn't know what to do with it, an error is displayed instead.

I recommend reporting this issue to the developers using the contacts details posted on the Contact Us page:
