Conflict?

JavaScript
1

I’m trying to install
http://www.styledisplay.com/scripts/slimpicker/demo.html
at http://fixmysite.us/masterasp/datepicker/moresheth-SlimPicker-e85691f/demo.html
But is there a conflict with
<script type=“text/javascript”>
$(document).ready(function(){
$(“.expanderHead”).click(function(){
$(“#expanderContent”).slideToggle();
if ($(“#expanderSign”).text() == “+”){
$(“#expanderSign”).html(“−”)
}
else {
$(“#expanderSign”).text(“+”)
}
});
});

$$(‘input.slimpicker’).each( function(el){
var picker = new SlimPicker(el);
});

</script>

Thanks…
cause I noticed t he thing doesn’t work when I add
$(document).ready(function(){
$(“.expanderHead”).click(function(){
$(“#expanderContent”).slideToggle();
if ($(“#expanderSign”).text() == “+”){
$(“#expanderSign”).html(“−”)
}
else {
$(“#expanderSign”).text(“+”)
}
});
});
