Here is the problem you forget Float: tag in enum:

pawn Code:

enum pInfo
{
    Pass,
    Money,
    Admin,
    Deaths,
    Skin,
    Float:Xpos,
    Float:Ypos,
    Float:Zpos,
}
new PlayerInfo[MAX_PLAYERS][pInfo];

EDIT:
Also fix this:

pawn Code:

INI_Float("Xpos",PlayerInfo[playerid][Xpos]);
INI_Float("Ypos",PlayerInfo[playerid][Ypos]);
INI_Float("ZXpos",PlayerInfo[playerid][Zpos]);
