I am trying to create a web app using Google app script, that if you press a button, you may get an alert message.

In the home.gs file I tried this :

function let_user_decide()
{
Browser.msgBox('Greetings', 'Press Yes or No?', Browser.Buttons.YES_NO);
};

unfortunately I keep getting this when I press the button when I should get the alert message :

Exception: Cannot call Browser.inputBox() from this context.

Important to mention : my script is using Google spreadsheet but the msgBox should appear in the webapp! In addition, I use HTML

Any idea what am I doing wrong? And how can I fix it?

Browser.msgBox is indeed only available in the spreadsheet interface, not in webapps.

You have a lot of alternatives to throw alerts but you should mention wether you use UiApp or HTML Service.

In UiApp you can create a popupPanel for example while in HTML you can throw alerts (throw new Error('sample alert')) or use JQuery Ui elements to do that.
