Forms 2.0 onSubmit Validation Script

[Anonymous]

When I use the onSubmit validation code from #9 on the Forms 2.0 page  the validation works. However when I change the value in the field that I am trying to validate the form doesn't run through the onSubmit again and the form is unsubmitable. 

View code below:

MktoForms2.loadForm("//app-abk.marketo.com", "###-###-###", 89,function(form){

form.onSubmit(function(){

   var vals = form.getValues();

   if( vals.verify != "Verify" || vals.verify != "verify" ) {

    form.submitable(false);

var verify = form.getFormElem().find("#verify");

form.showErrorMessage("You must type the word 'Verify'", verify);

} else {

form.submitable(true);

}

   });

form.onSuccess(function(values, followUpUrl){

   form.getFormElem().fadeOut();

   return false;

 });

});
