Hi, 

I have checked your website, and I can see that as soon as you resize the window, the form disappears completely.  

I checked your code, and it seems like main div containing the form has a value of min-width set, please see:

This could be the reason why your form is disappearing completely. Please try changing that value to a smaller number and see if that fixes the issue. Also, it is recommended to use iFrame method to embed forms into your page, as it will avoid any script conflict.

Here's how to get the iFrame code:
