I wanted to block the use of more than 4 numbers in a command of the announcement of my server.

I tried to do so
but gave an error

Код:

if(strlen(IsNumeric(result)) >4 )
            {
	        SendClientMessage(playerid,COLOR_RED,"The use of numbers");
    	    return 1;
            }

Anybody know how I can do??
