missing ) after argument list and unexpected token

I am using Harlowe 1.2.4 and Twine 2.1.3 and I'm getting an error on several mobile devices, the error (alert) is: "missing ) after argument list", while on other devices "Unexpected token =>". I believe that the issue is from the code below, the error didn't came up when I excluded this passage, however everything seems fine to me. Any solution or suggestion?

{   <div class="container home-menu">
    <div class="row content-1">
        <div class="col-xs-12 text-center">
            <!-- Menu -->
            <img style="height:90px;" src="res/images/splash_logo.png"/><br>
(unless: (saved-games:) contains $_autosave_slot and (datavalues: (saved-
games:)) contains $_autosave_filename)[(goto: $_start_passage)]
}''<span class="home-button">[[New->$_start_passage]]</span><br>
<span class="home-button">(link: "Continue")[(load-game: $_autosave_slot)]
</span>''<br><a href="#" onClick="closeMeNow();" class="home-
button">Exit</a>
            <!-- Credits -->
<div class="bottom-links"><a href="contact.html"><span style="color: 
white;">some text</span></a><br>
            <a href="credits.html"><span style="color: white;">some text</span></a></div>
        </div>
    </div>      
</div>
<script> function closeMeNow() { navigator.app.exitApp();} </script>
