Create a group box, then create your radio buttons within the group box. Only one radio button with in a group may be selected, and will cancel whichever button was selected.

You've posted in the Windows Forms forum and you're using MsgBox so presumably there is no "site". RadioButtons are specifically designed such that only one in any particular container, i.e. parent control, can be checked at a time. If you are really able to select multiple RadioButtons then they must be in different containers. Move all the RadioButtons you want to act as a set into the same container. A container might be a GroupBox, Panel, the form itself, a TabPage or any other control that can contain child controls.
