Hello,
I try to write a simple plugin reading a cvar from the client but i get errors and i cannot read the value

Whats the problem? (I also tried client_putinserver and also client_authorized but same problem..)
PHP Code:
#include <amxmodx>
#include <amxmisc>
#include <engine>
#define PLUGIN "TestingCvarPlugin"
#define VERSION "1.0"
#define AUTHOR "test"
public plugin_init() {
register_plugin(PLUGIN, VERSION, AUTHOR)
// Add your code here...
}
public client_connect(id)
{
client_cmd(id, "say %s", "testing cvar reading from client");
query_client_cvar(id, "zoom_sensitivity_ratio", "get_zoom_result_func");
}
public get_zoom_result_func(id, const cvar[], const value[])
{
new name[32];
get_user_name(id, name, 31);
log_amx("Client %d(%s)'s zoom_sensitivity_ratio is ^"%s^"", id, name, value);
}
and the error message on the console is:
PHP Code:
Host_Error: UserMsg: Not Present on Client 58
Can't "say", not connect
I understand the second message; if i cannot connect, i cannot send a command like "say" but what does thie means? "Host_Error: UserMsg: Not Present on Client 58" and how can i solve this problem?
Thanks..
