Thank you for sharing your project.
ActivePresenter uses Internet Explorer (IE) for previewing in Player Settings window.
Your script has arrow function in On Click event of Submit object (
cV.texts1.every(a => (...)), but IE doesn’t support it so you see this error.
Replacing it by a normal function will resolve this error.
You can check the error by previewing your project in IE browser.
Please be noted that IE doesn’t support many other ES6 features, so you should not use ES6 if you want to preview in Player Settings window or IE browser.
