Jquery append:syntax error

JavaScript
1

i am trying to generalize a function
function fill(thisValue,thisValue1,content_type=3) {
//var suggest_box=‘suggestions’+content_type;

	var box1='country6'+content_type;
	
	$('#country63').val(thisValue);

	setTimeout("$('#suggestions3').fadeOut();", 600);
}

what i want is some thing like
$(‘#box1’).val(thisValue);
setTimeout(“$(‘#suggest_box’).fadeOut();”, 600);
to work so that it is more generic but there are some syntax error

there is
<input type=“text” id=“country63” value…/>
how should it be done
i did some trail and errors …no success…
thanks
