How do I measure a URL in a funnel that contains variable data in between? wordtomeasure/variable/wordtomeasure

Hi,
I want to measure a link that contains variable data in between. What do I have to use? The following isn’t working for me and I can’t figure out what I’m doing wrong.

I want to measure those links as a funnel step:
www.ourwebsite.nl/gemachtigd-worden/633/belastingjaar2018/wie
www.ourwebsite.nl/gemachtigd-worden/24/anotherdienst/wie
Etc.

I used URL contains with: \/gemachtigd-worden\/(.*)\/wie
This isn’t working.

Can someone help me with this?

Thanks!

Aline
