creating a pop up alert

[TAG]

I am trying to create a pop up alert when certain criteria are met. My code is not working and I wonder if you can look at or recommend some code that does work.

How do I send you code to look at?

Alert test code

Here is the code I am trying to develop to pop up a window. What am I missing? Am I on the right track here?

var versionString = "1.00";
/****
* Alert Test v1.00 ATT 1.00.efs
*/
var barNum = 0;
var alertCount = 0;

function preMain() {
setPriceStudy(true);
setStudyTitle("Alert Test ver " + versionString);
}

// Main
function main() {
barNum = getCurrentBarCount();
if (barNum < 20 || alertCount > 3) return;
if (sma(6) > sma(14)) {
line = "Test Alert \n";
line += "\ t SMA(6): " + sma(6) + "\n";
line += "\t SMA(14): " + sma(14) + "\n";
line += "\t BarNum: " + barNum;
Alert.addToList( getSymbol(), line, Color.black, Color.white);
debugPrintln("\n---\n" + line);
alertCount++;
}
}

The reason you are not getting any popup alerts on historical bars [while the script is loading] is because the Alert.xxx functions execute only on bar index 0 (or bar index -1 when setComputeOnClose() is used)
