Hi Jade,

I think I have discovered what happens to your Javascript. Here is the correct Javascript...

var player = GetPlayer();
var a = player.GetVar("pct");
var b = player.GetVar("n");
a = Number.parseFloat(a);
b = Number.parseFloat(b);
x = a-(1.96*(Math.sqrt((a*(100-a)/b))));;
y = a+(1.96*(Math.sqrt((a*(100-a)/b))));;
player.SetVar("CILower",x);
player.SetVar("CIUpper",y);

You do nothing wrong, the variable becomes a string and you have to convert the string into a variable with the Number.parseFloat() function. If you don't want decimals, use the ParseInt() function.

Hope this can help you
