You only need to call one of those scripts. All you need in startpage.pstpl is:
<script type="text/javascript" src="{TEMPLATEURL}jquery.Rut.min.js"></script>
I would handle this as follows:
1) Change the plugin event to "change"
2) Disable all other text inputs on the page
3) If the RUT validation fails, alert the respondent
4) If the RUT validation passes, enable the other text inputs
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
var text = 'Rut Incorrecto';
var rutInput = $('#answer44855X13600X148215');
$('input.text').attr('disabled', true);
$(rutInput).attr('disabled', false);
$(rutInput).Rut({
on_error: function(){
$('input.text').attr('disabled', true);
$(rutInput).attr('disabled', false);
alert (text);
},
on_success: function(){
$('input.text').attr('disabled', false);
},
format_on: 'change'
});
});
</script>
