Question en attente de réponse

A1 form issued by MGEN

I am from the human resources department of Palacký University in Olomouc, Czech Republic.
Our Faculty of Science of Palacký University in Olomouc has started to employ French citizen who will do his research from France.
We have already received an A1 form which was issued by MGEN, Le Mans Cedex 2.

Problem is when we try to go through the registration on we can not to choose your company in the form. Not sure why this happens.

Anyway, we have to fulfill this form to pay social and health contributions in France.
That's why we would love to if someone contacts us to help us to finish this whole process.

Thank you very much for your response.
Best regards,
