Friends, can anyone help me connect Phoenixminer to Sparkpool?

I'm connecting to eth-eu.sparkpool.com:3333 and that part is ok. But I don't know the syntax to use to connect my worker and attribute the mining profits to me.

My worker name is sp_workername

Should I add sp_workername.1234 or just the bare name? In the docs it says:

Config Address and RigID
Format: Sub-account/address+ / +rigID. For example: sp_workername.1234

Should I add my Ethereum wallet address anywhere, or just the worker name?

Full syntax please
