Need help with clipping mask
I tried to use clipping mask for my drawing but something is not working right on adobe illustrator (it worked on photoshop...)

K what I wanted to do is to cut Darker lines(paths) which are going over the lighter ones by using clipping mask.
What I wanted to get was something like this (I deleted paths to show you what I wanted to get what I was expecting... I can't obtain this using clipping mask)
but what I get using Ctrl + 7 or clipping mask (selecting two layers) is this lol ...
It's weird on PS it worked fine but on AI I can't make this work.
What ever I do using pathfinder or switching layers position (darker layer going up , darker layer going down or what ever)
I just can't get what I want
Can some one help me plz
I must decide fast if I have to switch back to PS or learn AI and use it. If this doesn't work I'll have to say Goodbye to AI
