restore the tour variation adaptation

Hi, you made the adaptation to my site and when I updated the theme, the code was lost.
I made a backup but I don’t know witch file has the adaptation code.
Can you help me restore this, please?

Here is the ticked if we talk about this job.

Link "Tour Variations" to the total number of tickets

and here is my all backup file: https://wetransfer.com/downloads/4b41b1c0f239dad220bc8855942dc86420181228231636/d3640b9c7ce945ae66882f2537c9566a20181228231636/0905b6

If you prefer, I can download just a few files to be heavy.
