Make text bold

Hello, I wonder if you guys.girls would be kind enough to help me. I have some code, but I need to make the " Total price will be :$xx " text to be in bold.

Here is the code I have atm

<script type=text/javascript>
function getTotal(){
var form=document.theForm;
var inputs=form.getElementsByTagName('input');
var length=inputs.length;
var total='0';

for(i=0;i<length-1;i++){
if(inputs[i].type=='radio'){
var checked=inputs[i].checked?1:0;
if(checked){
var value=inputs[i].value.split("~~")[0];
total-=-value;
}
}
}
document.getElementById('totalspan').innerHTML="Total price will be: $"+total
total='0';
}

</script>


</html>

document.getElementById('totalspan').innerHTML="<strong>Total price will be: $</strong>"+total

Or add the following into your CSS
#totalspan{
font-weight:bold;
}

Thank you so much. You are most kind.
