All I'm trying to do is make a simple command that will resize my chat window to a specific size. Anyone think they can help me finish it? I'm kind of lost at the errors I'm getting. This is what I have so far:

code:

---

function OnEvent_ChatWndSendMessage(ChatWnd,Message)
{
    if (Message=="/sfix"){
        SetWindowPos(ChatWnd.Handle, HWND_TOP, 0, 0, 700, 500, SWP_NOMOVE | SWP_NOZORDER);
    return"";
    }
}
