This does not see to work for me,

var alarm = System.getGlobal("alarm_set.Initialised");
var time = GUI.getDisplayTime();
CF.widget("time").label = time;
CF.widget("time_alarm").label = alarm;

if (alarm == time) {
CF.widget("alarm_set").label = "exicute";
}else{}

got it working, needed to use ===

Your statement that you had to use === makes no sense. Something else in your code must be wrong.

System.getGlobal 'Purpose' from DEV Guide

Retrieve a string value stored in the global variables list.

Return
String
The value of the global variable, or null if the name is not found.

In your case, either the value returned was null or maybe had some extra characters on it.

null == 'hello' => false
null === 'hello' => false

The double equal does type coercion and null and a string are not the same.

Sounds like the first time you did this, maybe the global was not set prior to your executing the script but sometime after, it was.

But the alarm clock only works with ===, I have been using it for over a week and works every time, never locks up the remote and or mis launches. That is the entire script the repeats every 50 seconds when that page is displayed. I will go back and try it with == and see if it works now, maybe I made changes after the fact and never changed it back, either way it works.

All I was saying is that === vs == was not the real fix in case someone reads your first response. If you prefer, I can delete the whole thread.

I'm sure your right, I shouldn't be doing this at 2am anymore. LOL I did change it back to == and it works, like you said I must have changed something else. I also just realized that the Variable "alarm_set.Initialised" is Null when the page first loads, and stays Null till I interact with the page, so not sure if === vs == would make a difference there. Eiter way I fixed the Null factor, changed it to == and all is working.

Thanks for all your help you always know best.

The === means that the left and right hand sides must be the same value AND the same type.
