My files are a bit different than yours, but I got mine working. I noticed that you deleted the second inclusion of inc_func_posting, they specifically said that it was necessary to leave that in. May want to consider putting it back.
I modified the checking routine a wee bit to say:
I included inc_func_common.asp in my privatesend_info.asp
Here are links to the two files in .txt format:
