Code:
mob
    var/Health
    Login()
        if(fexists("User"))
    player
        var Health = 10


Problem description:

It may not seem like much, but what it's giving me is hassle because it won't overwrite it, anyone know what the issue is?

You need to define the variable once. It is inherited to all the children of that parent. Y'know, typical objective-oriented programming.

mob
   var/hp = X   //  all /mob children have this variable
   player
      hp = Y   //  Redefine's the default hp value that was inherited
      var/sp = Z  //  This variable is available to the parent + children of /mob/player

Code:
mob
   var/hp = X   //  all /mob children have this variable
   player
      hp = Y   //  Redefine's the default hp value that was inherited
      var/sp = Z

Zombie Survival.dmb - 5 errors, 0 warnings (double-click on an error to jump to it)

Those were the exact errors I got usng your precise code. You were saying?

This forum isn't for copy/pasting code, he gave you a general example, you weren't meant to use that exact snippet.

X, Y, and Z were examples.
They might be 1, 2, and 3. Or 100, 50, 20. Or maybe "cake", "pie", and "cheese". Although having a string to represent hitpoints would be kind of odd and unfunctional.

Sorry. I just get frustrated with coding sometimes.
