A little problem with llInstantMessage

http://pastebin.com/m488cf98c
The problem is at the very bottom in the http_response, i placed some notes.

The problem is that you are trying to send the IM to the wrong key. The llHTTPRequest function generates a key for the request. THAT's the key that the dataserver event is receiving. If you want to send an IM to an avatar, you have to use the avatar's key, not that one.

How can I pass the avatars key to the http_response state?

I got it.

I set a key in the beginning, then I change the key when its ran. It can be used anywhere in my script now.

When you make a llHTTPRequest call, the call creates the key. Just assign it to a variable....

key CallOne = llHTTPRequest(url ,[HTTP_METHOD,"GET"],"");

Your dataserver will receive any calls it gets from any llHTTPRequst function, so you may want to filter to be sure that it's responding to YOUR requests instead of those from another script, and you may want a different action from different calls in your own script. So you write

 
http_response(key request_ id, integer status, list data, string body)
{
if (request_id == CallOne)
{ // Do stuff}
else if (request_id == CallTwo)
{//Do different stuff}
else
{return;}
}

Yes, and in fact you could use a different key for each llHTTPRequest in your script if you wanted to. That way, you could tailor the actions in the dataserver event to do different things for each call (IM a different avatar, for example, or send a different piece of information). Incidentally, it's a good idea to build a test into your dataserver event to be sure that it's listening to YOUR calls, even if you use the same key for each one.

dataserver (key request_id, integer status, list data, string body)
{
if (request_id == myHTTPRequest) //myHTTPRequest is the key of your call
{//Do stuff}
