I have been seriously overbooked lately, but I made time between two web projects to dispatch a minor act of stupidity (mine). The dates in the period table are intended to be YYYY-MM-DD (4 digits year, a dash, 2 digits month a dash, two digits day). If you enter the month as only one digit the period selection did not work properly.
You can have this fix now if you email me at promotions@jdnash.org: I'll zip the development /afbo folder and mail it to you. If you can wait, this fix and others will be in the next update together with the automatic e-mail functionality.
On that note, I suggest you email me any changes or added capability (soon) that you would like in this next update. Barring AFBO emergencies I will start work on the update as soon as I finish my present web task.
