How to create instance of class that get data from 2 another instance?

[Suliman via Digitalmars-d-learn]

I have instance of class, that need data from 2 another classes. 
So I decided that I need to create it only after I get the data 
from both instance.

auto mysql = new MySQL(parseconfig, seismoDownload); // the 
problem is here! (LOC 170)

mysql need settings form parseconfig, and link from instance of 
seismoDownload class.

But I am getting error: undefined identifier parseconfig, did you 
mean class p
arseConfig?

What I am doing wrong?
