Javascript with html form hidding radio based on time

Hello All, I have a form page that needs some editing done to it. This is believed to be a simple edit for someone with javascript knowledge. I just don't have that knowledge! Here is my request. I have a form for picking football games. It interacts with MySql database to get selections that a player has made. Everything works correctly right now. What I want to do is make it so that it makes it so a player cannot change a pick after a game start. Example, if a game starts at 1:00 p.m. on Sunday, then at 1:01 p.m. on Sunday, they cannot change the pick they made. I believe it is a simple onload() and checks against the time/day for each game. I have set variables for each game(up to 16 games per week) for the day and time. If you think you can do this, please let me know. I am including the file so you can check it out and have a better idea if you can do it. If interested please bid. Thank You, Patsman77
