Can you fix vis tag_jump.lua, I can't sleep lol

[mudokenking]

More of an obsession than a requirement.
This ctags plugin doesn't work, it just keeps saying tag not found: https://github.com/kupospelov/vis-ctags
Your tag jump plugin (with what I tried to fix) works, but it doesn't jump, it shows me a correct list though.
here's what i have so far. P.s. I'm not a coder. Sorry for any novice mistakes (like preferring one-liners instead of indenting)
