RadioButton List need help.

[deepsanj]

Hi,
I am designing a webpage for making donations.There are 2 types of donation Legend and Gaurdian. Each type has 3 choice of payment amounts. The requirement is that I can select only one type donation.
Now I have created 2 RadioLists(LegendRadiolist and GaurdianRadiolist) each containing 3 radiobuttons.How do I uncheck(not disable) the GaurdianRadioList when the LegendRadioList is selected and vice versa.
How do I get values of each radiobutton clicked?Please help.

Thanks
