Need help creating an EFS. Never coded before in life.

I tried to do this for 4 hours last night but completely failed. Can anyone help me with what I want to do.

Basiscally I want an alert to be issued when 3 criterias are met. The first criteria is that the MACD (2, 3, 1) be below -.001. The second criteria being is that the RSI (2) index should be below 15. And the last part is the hardest part it is a script I found on the forums that plots the linear regression in an osccilator-like
manner. I would like that to be below -.01.

I tried to do it with just the 2 basic studies (MACD and RSI) and couldn't even do that... let alone the 3rd study. ANY help would greatly be appreciated. The code for the linear study is attached. I forgot who created it so sorry for not giving credit.

Hey I got the first 2 to work. I don't know why it wasn't working before. But it works now. My question now is how do you get a value from a study that is not included as a "built in" in the formula wizard? I want to add a 3rd condition that gives linear regression a value. How do I call upon that script? Here is what I have so far:

//{{EFSWizard_Description
//
// This formula was generated by the Alert Wizard
//
//}}EFSWizard_Description


//{{EFSWizard_Declarations
var vMACD2_3 = new MACDStudy(2, 3, 1, "Close", false);
var vRSI2 = new RSIStudy(2, "Close");
var vLastAlert = -1;
//}}EFSWizard_Declarations


function preMain() {
/**
* This function is called only once, before any of the bars are loaded.
* Place any study or EFS configuration commands here.
*/
//{{EFSWizard_PreMain
setPriceStudy(true);
setStudyTitle("ff");
//}}EFSWizard_PreMain

}

function main() {
/**
* The main() function is called once per bar on all previous bars, once per
* each incoming completed bar, and if you don't have 'setComputeOnClose(true)'
* in your preMain(), it is also called on every tick.
*/

//{{EFSWizard_Expressions
//{{EFSWizard_Expression_1
if (
vRSI2.getValue(RSIStudy.RSI) < 10 &&
vMACD2_3.getValue(MACDStudy.MACD) < -.003
) onAction1();
//}}EFSWizard_Expression_1

//}}EFSWizard_Expressions


//{{EFSWizard_Return
return null;
//}}EFSWizard_Return

}

function postMain() {
/**
* The postMain() function is called only once, when the EFS is no longer used for
* the current symbol (ie, symbol change, chart closing, or application shutdown).
*/
}

//{{EFSWizard_Actions
//{{EFSWizard_Action_1
function onAction1() {
Alert.addToList(getSymbol(), "BUY!", Color.RGB(0,0,0), Color.RGB(195,0,0));
vLastAlert = 1;
}
//}}EFSWizard_Action_1
