Forum OpenACS Q&A: Response to Polls error
It seems this function would be a tad bit more robust if it stripped and leading zeros off of the day... I've just checked in a new version of ad-aolserver-3.tcl.preload that does this. This problem would only occur for the 8th & 9th of the month. So good thing you didn't wait until Wednesday to add a poll!
(If you are running AOLserver 2.3, and not 3.0, then my changed ns_buildsqldate code won't do you any good, and you'll need to poke around in modules/tcl under the AOLserver home and find where it is declared.)
