Issues with medical visualizer functions

I just realized you were new to the forum.
Welcome!

When users have questions on projects it is always best to share a link to the project you are working on or write code directly into the forum if it is a small code snippet.

Instructions for writing code in the forum:

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').
