Please when you have a time read all community guides.
Anyway you can start from here:

How to ask a question?

Asking questions To improve the chance of getting help on the forum please follow these recommendations when posting a question: Do your homework first Search for similar questions/answers on the forum. Try forum search and also Google your problem. Try to solve the problem yourself, and describe what you have tried. It is much more rewarding to help someone who has tried himself first. Post in the right categorie, post only once and do not steal topics Make sure that you post your question …

Last point of How to ask a question ?

• Kodular Community is a place for koders around the world. Everybody has to be able to ask, reply and understand all questions which may affect them
  This is the reason why English is the unique allowed language in public posts.

Thanks so much. Hug.
