I don’t understand what you are trying to do here. Please provide an MWE, with desired inputs and outputs.

> Welcome to the Julia Discourse! We are enthusiastic about helping Julia programmers, both beginner and experienced. This public service announcement (PSA) outlines best practices when asking for help. Following these points makes it easier for us to help you and more likely you’ll get a prompt, useful answer. Keywords are highlighted to make it easier to refer to specific points. Choose a descriptive title that captures the key part of your question, eg “plots with multiple axes” instead of …

Also, note that the second `Initializer` overwrites the first (is this intended), and globals are unlikely to be the right approach.
