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?
