DDE output of prior bar data

[fish7]

I have written a very simple EFS to get the value of the CCI indicator, using Alexis' EFS. It works great, but I want to access the CCI values from one and two bars prior. How do I do that?

Below is my EFS code.

Thanks for any help.

var vCCI = null;
var dde1 = new DDEOutput("CCIvalue1"); //This is for DDE output to Excel file

function preMain() {
setStudyTitle("CCI for DDE"); //Sets the title in the formulas pullout on charts
setCursorLabelName("CCI for DDE", 0); //Sets name in cursor window
}

function main() {

if (vCCI == null) vCCI = new CCIStudy(14, "HLC/3");

dde1.set(vCCI.getValue(CCIStudy.CCI)); // Assign current CCI value to the DDE
// HOW DO I GET THE CCI VALUE FROM ONE BAR PRIOR???

return vCCI.getValue(CCIStudy.CCI);
}

vCCI.getValue(CCIStudy.CCI,-1) gets you the value of the CCI at the prior bar, vCCI.getValue(CCIStudy.CCI,-2) that of two bars ago, etc

Ahh... I got it... the "getValue() function allows for a bar index input. So I changed it to:
getValue(CCIstudy.cci, -1) for the cci value of the prior bar.
