Querystring Parameter contain brackes tx_mmdb[cat]= 37201, but in Web Companion I get tx_mmdb%5Bcat%5D= 37201 which can be assigned as data source.

"Name can only contain letters, numbers, underscores, dollar signs, array brackets, periods."

If I change this to brakes nothing happens.What can I do?

Hi @Schlingel, I don't see that in web companion, I see: 

What browser are you using? 

Alternatively, if you add it as a querystring parameter directly in TiQ Data Sources, it should work. 

Many thanks
