<p>Hi! We would pay for your advice because we have an urgent issue. We use our old template file and everything works but if we add new data binding, it doesn't work. Tried everything, please could you help? We can talk via skye, I'm perfect in English. And we can pay you! Thank you very much in advance, regards, Zoltan</p>
