Help JavaScript please

Nightblade

So this is literally the first time I've ever tried to code JavaScript so be gentle with your responses, please

I'm trying to get CSD to roll some dice for some values on my sheet. So I wrote up a little JavaScript that looks like this to try & roll a d5:

function HitDice ()
{
         RollDice ( 1, 5, 0)
          }

And I put this as the Field Source (the field is named "HP"):

js.HitDice (HP.Value)

When I open the Sheet up in the viewer, I get the folowing error:

Native Expression Error: HP
Error: Invalid Expression
Expression: js.HitDice

So what am I missing? Or is there an easier way to have fields roll dice values that I don't quite understand from the Help file?

Thanks in advance!

For the field source, I believe it should be set like:

js:HitDice(HP.Value)

(ie, a colon, not a period)

And then your function, you need to return the value. So something like:

function HitDice( d)
{
   return RollDice ( 1, d, 0)
}

Also, since you're using HP.Value, you need to have a field called HP on your sheet that has a value in it (like '8')
