mutually exclusive checkboxes

Hi,

I am writing code to make two checkboxes mutually exclusive. It works, but one cannot uncheck the checked box if one decides. It basically treats it as Radio button which is not what the desire result should be. Here is the code.

if

(this.rawValue=1)

{

= 0;

}-------for the first checkbox

And

(this.rawValue=1)

{

= 0;

}

for the second.

Is there anyone out there who knows what I may be doing wrong?

Thanks

LP
