I found the below code in this forum. Author adios. It works fine, but I need it tweaked. How can it be modified to hide multiple rows with the same id tag? I use ASP classic and generate like id's for the rows I want to hide, but this will still only hide the exact row on which my link is. Guessing, it hides the first id and stops instead of hiding them all. I know nothing about javascipt so any hand holding would be appreciated.

thanks!
