Scraping Sequential Pages that present content differently

Hey all,
I am trying to scrape a large forum. However, it appears that the older entries have the username presented in a different way. When I encounter the change while scraping, screen scraper will no longer write to my text file. :cry: It gives me a permission denied error in the log.

I think this is because it has no data to write for my AUTHOR token. I tried writing a vbscript that re-scrapes the page with a different scraping session IF AUTHOR = NULL but so far I've had little success.

I am also running an increment so that I can scrape numerically named posts. It took me a while, but I got that working fine. Any ideas on how to incorporate this IF THEN into that logic would be greatly appreciated.

Thanks,
McFly
