I thought if you hit the "cancel" button it cancels
the script or does it just cancel the dialog?

try
set v to cell "g_vendor_id" of current record
set the user_choice to the button returned of the result
{display dialog "Do you wish to create a Lettershop P.O. for
Vendor ID#"&
" "& v&"?" default button 1 buttons {"okay","cancel "} with
icon 2}
end try

Pressing the cancel button in "display dialog" causes the command to throw a "user canceled" error. It's then up to you to either catch the error using a try block and deal with it, or don't and let whatever called your script deal with it. In this case, you've put the "display dialog" call inside a try block with no error handler, which causes all errors to be ignored, so your script continues merrily on. If you want "cancel" to stop the script, removing the "try" and "end try" will probably do the trick.

P.S.: Is there any particular reason you put "display dialog" inside a list? It shouldn't make any difference, and it's sort of weird.
