How to make the rest inactive and empty when selecting a checkbox in VBScript?

Question

HTML

On a normal html page there are several checkboxes like

<input id="All" type="checkbox" checked />
<input id="Valid" type="checkbox"  />
<input id="Dissolved" type="checkbox"  />

How to make it so that if one of them is selected, the rest are not available, preferably in VBScript (although it is possible in other languages, if it is more convenient there)
And why when I try to check whether it is selected or not, I get back a value of the form True\False instead of True\False?

allContract = document.getElementById("All").Checked

Use radio buttons.
