ok i have a problem with my code when i try to compile i get the following errors [ EXCEPT OR FINALLY expected ] and [ ';' expected but ',' found ]

can anyone help?

thanks alot

You started a block of code to trap any errors by using the keyword "Try".
However you have not completed it by using "Except or Finally" (see code marked in red)
