Javascript onsubmit script / string

I have an onsubmit process that looks like

<form onsubmit="return confirm('Are you sure you want to change the dates on this reservation to those new dates?');"

What I'd like to do is change that string to incorporate some text from some form fields in the document.

I tried

onsubmit="return confirm('Are you sure you want to change the dates on this reservation to '+document.getElementByID('datepicker3').value+' to '+document.getElementById('datepicker4').value');"

but alas - it didn't work nor have any of the other variations kinda similar to that.

What am I missing?  

Thanks in advance!

or for easier readability, move it to its own function:
<form onsubmit="return checkForm()">
...
</form>
<script>
function checkForm() {
    var dt3 = document.getElementByID('datepicker3').value;
    var dt4 = document.getElementByID('datepicker4').value;
    return confirm('Are you sure you want to change the dates on this reservation from '+dt3+' to '+dt4);
}
</script>

Your statement has an extra tick mark... is that in the code? Breaking it up for readability, it looks like this:

onsubmit="
return confirm(
'Are you sure you want to change the dates on this reservation to ' +
document.getElementByID('datepicker3').value +
' to ' +
document.getElementById('datepicker4').value'
);
"

See the extra tick mark at the end of the bolded part?
