		<description>&gt; javascript fails with a â€œNaNâ€? error

hope this helps.

var prevScaledTime = outputs[0];
var speed = Number( inputs[0] );
var dummy = Number( inputs[1] );

if( prevScaledTime == undefined )
{
	prevScaledTime = 0.0;
	outputs[0] = 0.0;
}
else
{
	outputs[0] = prevScaledTime  + speed/100.0 + dummy*0.0;
