I'm still struggling with this, and I'm wondering if loading the JavaScript externally would solve the issue:

I'm not all that great with JavaScript, so I'm not 100% sure I can make this work. Does anyone know if this would be worth pursuing? I'd hate to go down this path only to learn it was never even possible to begin with.
Thanks!
