Im bad with Radio buttons

[chico1st]

Okay I have a form and I have 2 radio buttons on it
Each radio button corresponds to a text box so I have a script that will check the buttons depending on which text box gets clicked
but I have 3 problems.
1) I need the script to go off if you tab in as well
2) I need the other radio button to get unchecked if you check one but that doesnt do itself.
3) I have an uncheck function that I can use but i dont know how to put 2 functions into 1 onclick trigger. And it seems taht if i use 2 onclick functions the 2nd one doesnt trigger.
Any help would be awesome
THANKS A TONNE

PS thanks for the help earlier corbin

if those buttons are placed in a single form, then no problem. can you show me some codes?
