Hey there, thanks for the response! Yes the call couldn’t be more simple, just this in the template body:
<script>
jQuery(document).ready(function($){
some_function();
});
</script>
So surely that should work?? I checked my source and ajax.js is there, although when I view the file, it’s got a load of webkit stuff in as well as my simple function - is that normal??
It’s still telling me that some_function is not defined though
