the identifer of a global variable has to be unique.

meaning something like

pawn Код:

#include    "a_samp"

main(){}

new random_stuff;

public OnGamemodeInit()
{
    new random_stuff;
    
    return 1;
}

will throw the same warning.
"warning 219: local variable "random_stuff" shadows a variable at a preceding level"

this means that somewhere in your script is a variable by the name "playerid"

search for it and get rid of it.
especially "playerid" as identifer... really bad choice if it's a global one,
as most of the callbacks contain a "playerid" param.

also, generating too much global variables isn't good.
Stuff will get messy after some time.
Try to stay local & use pointers wherever you can

also, i suggest using a switch instead of these endless control structures
