FYI, I believe I fixed the above problem, but still need to upload the changes to github... Wanted to run a couple more tests as well. Did find that the solution for the date/time issue was partially incomplete as I found cases of 0000-00-00 00:00:00 entered for the date_available related field instead of NULL, but at least it doesn't "seem" like it causes a problem by being there... Still to be incorporated/updated regardless of what it "seems". :)
