How to cange text on next or previous buttons

If you want to change the text of the "Next" or "Previous" buttons, e.g. at the end of the survey to say something different, you only need to add an HTML element to the question or info with the following:

For the "Next" button to show the text "Submit":

<html>
<script>
function pageReady() {
   $('#btnNext').val("Submit");
}
</script>
</html>

For the "Previous button" to say "Please go back":

<html>
<script>
function pageReady() {
   $('#btnPrevious').val("Please go back");
}
</script>
</html>
