i just copied this code but when i click on the rad2,it can't checked.
i just copied from the 2nd post's code as the code defaultchecked is set to rad1.
i can't select rad2 or rad1, as it is always checked at rad1.
I know the defaultchecked is when i enter the page, the radiobutton is checked by default.
but the radio button can't let the user choose either of them.
when the user click on 1st radio button, then checked this button, and set the 2nd radio button checked to false.
if 2nd button is checked, then set the first button checked to false.
only one of them checked.

but now when i code rad1.defaultchecked=true, it is always true, even i click another button, it can't change the checked value to the button clicked.
I would like to do a validation check for textbox field.
only let the user input number range or just a number in the following format:

1) 11,12
2)1-10,11-20
if the user input 1 to 10, or other than the above format, then prompt a msg.
thanks for your help.


but when i check another radiobutton, it seems can't appear checked.
the checked always appear in the first radio button. can't choose second one.
