Call Function on Main Timeline from Global Script

[RyanS_Extron]

I have this on the main timeline:

function sayHi () {
	alert ("Hi");
}

I even tried this:

this.sayHi = function () {
	alert ("Hi");
}

In Global Script, I tried:

window.exportRoot.sayHi();
window.sayHi = exportRoot.sayHi;

I'm just shooting in the dark right now. I tried following these two posts:

Run local function from global function 

Call function from external html? Animate CC 

The reason why I need to call a function from the Global Script is that I can access Global Script using Captivate, but not any function inside the inserted Animate oam. Thanks.

I finally found a way to access inside Animate by clicking on a button in Captivate. I added more to the code to test accessing a function contained inside Animate. First, I created a variable in the Global Script:

var sayHi;

Then, I have this variable equal a function in the timeline. The function created will call another function. The code below is all in the Actions panel in the main timeline. I happened to place it in frame 1:

sayHi = function () {
	letsGo();
}

function letsGo () {
	alert ("Let's go!");
}

Finally, I used this code to call the variable in Global Script containing the function:

var win = document.getElementById('myFrame_Web_5c').contentWindow;
win["sayHi"]();

"Web_5" is the ID for my Animate that I published as an .oam and then inserted into Captivate. I called it "Web_5" in Captivate, but to get its element, I needed to suround it with "myFrame_" then "c" since the oam is located in an iframe. Hopefully this will help anyone else needing this solution. Maybe someone else has a simplier process, but I couldn't find any post explaining this.

What's the purpose of using bracket notation in the function call? That should be functionally identical to:

win.sayHi();

When I use:

win.sayHi();

it doesn't work. I just retried it right now to make sure. I found the other solution here: https://stackoverflow.com/questions/1723287/calling-a-javascript-function-named-in-a-variable
