How can I use multiple connected variable in ADF to be pass in my Databricks notebook

Hi,

I need 3 connected variables which I need to use in my databricks notebook. 

This is the context of the variables that I need:

filepath: root/sid=test1/foldername=folder1/

sid: path identifier, this is needed so only correct files in the folder will be loaded

foldername: every "sid" may have multiple folder so I need to identify the foldername. I will also use this to partition my data for duplicates

tablename: this is the target table where I need to load the files

Basically, the two variables are predefined which is stored in a csv file.

My source which is in blob storage looks like this:

And this is what I want for my variable

Looking forward to your help.
