BB and Keltner Channel

[mzafka]

I am combining Keltner channels with BB. If I add the condition at the end to play a sound each time the BB is inside the Keltner Channel it does not work. I am missing something and I do not know what. I am relatively new at this. I am just good at combing/editing existing scripts. Thank you kindly.


var fpArray = new Array();
var bInit = false;

function preMain(){
setPriceStudy(true);
setShowCursorLabel(true);
setShowTitleParameters(false);
setStudyTitle("Keltner ATR Band & BB");
setCursorLabelName("Up Band", 0);
setPlotType(PLOTTYPE_LINE, 0);
setDefaultBarFgColor(Color.red, 0);
setCursorLabelName("Dn Band", 1);
setPlotType(PLOTTYPE_LINE, 1);
setColorPriceBars(true);
setDefaultBarFgColor(Color.red, 1);
var x = 0;
fpArray[x] = new FunctionParameter("Length", FunctionParameter.NUMBER);
with(fpArray[x++]) {
setLowerLimit(1);
setDefault(13);
}
fpArray[x] = new FunctionParameter("ATRMult", FunctionParameter.NUMBER);
with(fpArray[x++]) {
setLowerLimit(1);
setDefault(1.3);
