Thanks for the reply. I tried as your suggested, but get a parse error on line 52 now which would be this line:
header("Location: ./index.php?go=$index_file";
It seems we're getting closer, but with little help from me, you're on your own. lol. Call me a newbie.
I did edit the $go in the Error Message, and might edit that entirely at some point after getting this default page situation.
I'm totally lost, and truly appreciate the help.
