fix a script

I have a script that had been running very well, but has started to give me error messages, and has stopped running smoothly. This script compiles data from 3 different websites, and stores the data in access, and then i filter the information according to my specifications and i receive various excel spreadsheet results. I believe that the reason i am getting the error messages is because the layout of one of the websites seems to be different, but i am unsure. I have the script.
