fixedHeader colum search error (Cannot read property 'top' of undefined)

Lucata

Hello,

When i enter a search value into my fixed header (after scrolling) it gives the "Cannot read property 'top' undefined" error.

I am aware that I somehow, somewhere need to take the offset into consideration, but I am not quite sure where!

I added a js fiddle to illustrate the issue.

How do i fix this?
