How do i check all of the checks except the one i clicked

[bzemer]

Hi,
i have 5 checks, what i want to do is like this;
when i click on a check, all of the checks goes to value=2 except the one i clicked and it becomes value=1. if i click on a different one then it's the same, all go 2 except the new one i clicked..

i don't want to use long messy codes and i keep getting my self into loops, so is there a quick and easy way to do this..?

thanks..
