Add custom class to Marketo form submit

[Callum_Pirie]

Sorry I just add the following into OptinMonster into Integrations and Custom HTML and then add the following

<script src="//app-lon08.marketo.com/js/forms2/js/forms2.min.js"></script>
<form id="mktoForm_1109"></form>
<script>
MktoForms2.loadForm("//app-lon08.marketo.com", "625-GXJ-187", 1109, 
function(form) {
    form.onSuccess(function(){
        om{{id}}.Analytics.conversion();
    });
    });
</script>

So you're using other code instead.  You do understand you're making this very confusing?

I thought that was the code you gave me? sorry I will just leave it then.
