Code:
mob
    Login()
        client.mob = new /mob/player
        var/client/mob/currentCash
        var/client/mob/currentName
        var/client/mob/currentRank
        var/client/mob/currentBranch
    
    proc
        createData(ckey)
            var/savefile/F = new("" + ckey + ".sav")
            F["cash"] << 0
            F["name"] << ""
            F["rank"] << 0
            F["branch"] << 0
            
        saveData(ckey, client)
            var/savefile/G=(""+ckey+".sav")
            G["cash"] << currentCash
            G["name"] << currentName
            G["rank"] << currentRank
            G["branch"] << currentBranch
            
        loadData(ckey, client.mob)
            var/savefile/E=(""+ckey+".sav")
            E["cash"] >> currentCash
            E["name"] >> currentName
            E["rank"] >> currentRank
            E["branch"] >> currentBranch


Problem description:
FOR STARTERS, DO NOT CALL ME A NOOB. If your angry and just wish I'd get the clue, don't help me. I don't need the attitude. But the problem is, that I'm having issues accessing vars. Above is my code, and what I can't seem to figure out is how I can access the variables assigned at login. Can anyone please shed some light on the situation.

Variables defined within a procedure (like mob/Login() there) are not accessible outside that procedure.

Also realize that by changing client.mob, the current mob will no longer be src (because you've changed which mob is theirs), and Login() for the NEW mob will be called.

Oh, I see. Thank you for at least pointing that out, I wasn't aware of that caveat to programming with BYOND. Thank you also for being polite in response.
    player
        icon = 'concrete.dmi'
        var
            currentCash
            currentName
            currentRank
            currentBranch


In either case, I defined it in the mob, what am I doing wrong still? >_> I'm sorry.

You defined it under /mob/player, which is also not visible for /mob/proc/whatever().

Where you define variables extends beyond just DM. Look up 'scope (programming)'.
