I need a simple bubble sort code because I need to program a button that the user can click to automatically sort the names
That's a complete non sequitur. Nobody writes their own sorting methods in this day and age. Bubble sorts are ancient history.

any idea how I can display the result in the output textbox from the highest to the lowest (top to bottom)?
Seriously? You can do a bubble sort but only in one direction? You have an array of values and you can only count forwards?
