Rooky question : use URL parameters

Hi all,

I use Grafana 4.6.3 and I’ve made my first dasboard, so I’m a beginer.
In this dashboard I put a “drilldown / detail link” to open another dashboard.

So the second dashboard have an URL like this :
http://xxxxxxx/dashboard/db/second_dashboard?from=now-5m&to=now&var-server=toto&var-FileSystems=("%2Ftmp"%20OR%20"%2Fappli%2Fao6%2Fvisualisation"%20OR%20"%2Fappli%2Fao6%2Fdonnees")&server10=dsddv569&refresh=5m&orgId=1

I try to get the value of the url parameter called “var-server” to use it in a template variable but I don’t understand how to do that ?

Help wanted !!!

I’ve made so much tries that it couldn’t work in this state.
I’ve start with a clean new one and it works.
Sorry
