Problem with contact form in popup

[kuki-design]

Hello!

Hope, you can help:

If I have a contact form in my header (working with a popup) and a contact form on a site, too, the datepicker choose the form on the site not the form inside the popup, no matter if you using the datepicker inside the popup.

Hope you understand what I mean?

Thank you very much for your help!

Regards,
Monique
