what is wrong ?

[CPLNet]

win_id = csgo
Process, Exist, csgo.exe
PID := ErrorLevel
DllCall("client.dll", PID)
WriteProcessMemory(csgo, addr, 0x674B98, 674B98 , 1)
{
if (csgo > 1)
{
addr += 674B98
write_success := DllCall("writeprocessmemory", "Uint", ProcessHandle, "Uint", addr, "uint*", addr_1, "Uint", 1, "Uint *", BytesWritten)
WriteProcessMemory(csgo, addr, 0x624410, 624410, 1)
}
}

If that is the whole script its obvious csgo variable is empty.
