 * Hi Guido,
 * after filling the form, adding correct number of sum field and submitting the
   contact form, it gives me a message “Please enter the correct result”. It works
   on second try.
 * How can it be solved, please?
 * thanks,

 * Hi Tibo,
 * Can you exclude the contact page from your caching and see if this solves the
   problem?
   (I see that you’re using LiteSpeed Cache)
 * From their site:
   _Log in to your WordPress website >> Litespeed cache >> Cache
   >> Exclude >> Inside the field “Do Not Cache URIs” add the pages that should 
   not be cached._

 * Hi Guido,
 * I did exclude whole contact page from caching, it seems to work;) Thanks!
 * One more question: after submitting the form and seeing message “Thank you! You
   will receive our response as soon as possible.” I have to click on contact page
   in top menu to see form again. Is it possible for message to disappear automatically
   after lets say few seconds and see form again?
 * thanks,

 * Hoi Tibo,
 * Great, caching and variable content (in this case the sum) often causes problems.
 * To answer your question, no this is currently not possible. But I will look into
   this.
 * I did see something else at your site. The element that holds the form has a 
   fix height of 360 px. It cuts off the form when it’s not filled in correctly 
   and the red warnings are displayed.

 * I know, I want to have contact form same height as right container with image
   which is 360px. Not sure what can I do there differently. I will scratch my head
   about it tomorrow:) Any idea?
 * Anyway, thanks for your help, as always.

 * Hi,
 * Fixed height (and width) is tricky, because your site is displayed in various
   devices (= screen sizes). 
   In this case I don’t see a big problem, the form has
   almost the same height as the map next to it. The height only becomes more than
   360 px in case of a form error. So IMO you can remove the fixed height from the
   form container.
