Alternate Sidebar Issue

I am trying to do this same thing — use a different sidebar for certain pages, but am having an issue.

I created an alternative page and named it page-static.php

I created an alternative sidebar called sidebar2.php

Made two edits to page-static.php
Added template name
Renamed get_sidebar to get_sidebar2

When I select this template, I don’t have a side bar and get this error where the sidebar should be:

Fatal error: Call to undefined function get_sidebar2() in /home/snapprom/snap/html/wp-content/themes/abink-minimal/page-static.php on line 25

So I assume I have to define a function? Where and how?

I really appreciate this. I’m not a programmer. Know just enough to poke around and edit some things.
