Update -> Re:Kinda Urgent (to me, anyway) -> Javascript, postgres and checkboxes... Last big hurdle

[Madison Kelly]

With the generous help of you all and specially of Emma and Lance, I 
have this problem licked I think. I'll be working tomorrow to pull 
things together and work out bugs but it looks like I can finally move 
on after a three day delay.  :D

Public thanks to all and special kudo's to Emma and Lance!!
