Code:
obj/bar/healthOverlay
    icon='Healthbar.dmi';icon_state="overlay"
    pixel_y=38;layer=100;pixel_x=-1


obj/bar/health
    icon='healthBar.dmi';icon_state="health"
    pixel_y=38;layer=99;pixel_x=-1


mob/proc/healthCheck()
    var/obj/bar/healthOverlay/o=new()
    var/obj/bar/health/h=new()
    var matrix/m=new()
    src.overlays-=src.healthBar
    src.overlays-=h;src.overlays-=o
    src.overlays+=o
    m.Scale(src.hp/src.maxhp,1)
    h.transform=m
    h.pixel_x+=(((src.hp/src.maxhp)-1)*10) * (((h.bound_width/2)-1)/9.5)
    src.healthBar=h
    src.overlays+=h


Barcode.dm:16:error: src.healthBar: undefined var
Barcode.dm:19:error: src.hp: undefined var
Barcode.dm:19:error: src.maxhp: undefined var
Barcode.dm:21:error: src.hp: undefined var
Barcode.dm:21:error: src.maxhp: undefined var
Barcode.dm:22:error: src.healthBar: undefined var

Problem description:
I was watching a tutorial https://www.youtube.com/watch?v=cm_yYWNLaOM&t=129s and i appear to have done something wrong and have tried many things to fix it but it just wont work, I wish to know if there is anything wrong here or if i should just try to find another way of making a healthbar.

Not to state the obvious but have you defined those variables already in the project?
for example

mob/var
hp=0
healthBar
maxhp=10

In response to Byakuya_uchiha32
mob/var
hp=200
maxhp=200
healthBar


sure did, i probably messed something up here somewhere o.o

are those variables located in a different .dm file from your healthbar code?

In response to Byakuya_uchiha32
Indeed they are.

try moving those specific variables to the same .dm file

...thank you LOL i knew i was gonna feel stupid after this xD

lol im glad it worked out. I don't know why thats happening because in theory it should work no matter where the variables are located unless you have that .dm file unchecked or not included while compiling.

In response to Byakuya_uchiha32
yeah xD

Whut? NO! It doesn't matter what file things are in!

Please share the snippet where you declare all your variable for your mob, it should look something like:
mob
   var
      hp
      maxhp


Also, I'd advise not writing:
A line of DM; another line; and another

as it makes your code much less legible, which means less maintainable, and more bug-prone. This isn't real estate, you're not paying per line, use whatever space you need ;)

im pretty sure he wasn't including the dm file the variables were located while compiling. its the only viable explanation

It'd be better to tick include on that DM, and keep the code structured sensibly than to teach him to bunch stuff together unnecessarily though.

It's important that we keep in mind that solving the problems here is not our only goal: we also need to help people become better programmers.
