As for your first error, symbol "Report" is already defined

pawn Код:

enum {
    Foo,
    Bar,
    Report
}

Foobar(Report[])
{
    printf("%d", _:Report); //Will return 2  
}

Rename your function parameter from Report to something else.

2 is identical, GetPlayerNameEx uses "ReportFrom" which is already defined in your enum.
