Checkboxes with the same name in Flash forms

["pope on acid" <alex.walgraeve@xxxxxxxxxx>]

This works fine until you add  [b]format="flash"[/b]. Can anyone tell me how to 
get this works in a flash form, please?

 <cfform format="flash">
        <cfinput type="checkbox" name="c" label="a" value="1" />
        <cfinput type="checkbox" name="c" label="z" value="2" />
        <cfinput type="checkbox" name="c" label="e" value="3" />
        <cfinput type="checkbox" name="c" label="r" value="4" />
   <hr />
   <cfinput type="submit" value="Zend" name="submit">
 </cfform>
