Don't use "value":

...
   put hilitedbutton of group "group1" into field "1" of CD X of  
stack "data sample"
## see below...
...

This will only return the NUMBER of the hilited button of that group
1
if the the FIRST button in that group is hilited and
2
if it i the second one.

You cannot "send" the value of a variable.
You can only "send" a message = the name of a handler.

So you just:

global dataValue1
on mouseUp
   PUT dataValue1 to field "1" of CD X of stack "data sample"
   ## see below...
end mouseUp


And try this for checking which radiobutton is hilited:

on mouseUp
    put empty into temp_var
   ## we willstore the NUMBER of the hilited button here

    if the hilitedbutton of grp "group1" = 1 then
      ## the first button = "yes1" is hilited
      put "YES" into temp_var
    else
      ## the secong button is hilited
     put "NO" into temp_var
   end if

  if temp_var = empty then put 0 into temp_var
## NO button is hilited!

  put temp_var into  field "1" of CD X of stack "data sample"
  ## if you omit the descriptor "of CD X" it will only work if the  
field is on
## the current card of stack "data sample" or it there is only ONE  
card in that stack!
end mouseUp

Hope that helps.
