Unchecking radiobutton if another is selected

hi…

I am using the FFP Lightweight components set tickbox (this component is available at flashcomponents.net)

for YES and NO questions…

I want to put script in each tickbox to uncheck the other box next it if it gets chosen (so a user can’t select yes and no)

I also want to add or subtract a value from a variable…

heres a sample of what i put on each tickbox instance… the syntax is definitely wrong:

on(release){

value = n14.getValue()

if value = (true)
(n14.setValue(false))
yellow -1;

else if value = (false)
(y14.setValue(true))
green++;
}

SOrry for my crappy actionscript… thats why i need help!!

also i need help with a script calculating the top three of the variables of color after the quiz is completed…
