Invalid key passed to IM?

Trying to avoid using SHOUT but only the owner im is working. the detectkey one is posting a an error stating Invalid Key Passed to Instant Message. Below is a clip of the code. Any clue?

if(gMyTRequest==id)
        {
            integer i;
            list lbody=llParseString2List(body,["\n"],[]);
            integer count=llGetListLength(lbody);
            //This turns newline characters char(10) into new lines in chat
            //These are Unix/LSL style end of lines, use \r\n in place of \n for
            //  Windows style end of line from web server.
            for(i=0;i<count;i++)
            {
               // llOwnerSay(llList2String(lbody,i));

                llInstantMessage(llDetectedKey(0),llList2String(lbody,i));
                llInstantMessage(llGetOwner(),llList2String(lbody,i));

                 //llShout(0,llList2String(lbody,i));
                 //llSay(0,llList2String(lbody,i));
            }
        } 

It would help if you indicated which event that code is in. From the wiki: The llDetected* functions will only return a meaningful value in the collision(), collision_start(), collision_end(), sensor(), touch(), touch_start(), or touch_end() events.

Hi Talon, my bad. its in http_response

I do get it in touch_start and that works. Am I out of luck if I need it in the http_response??

Thanks

I'm pretty sure that llDetectedKey will return NULL_KEY inside http_response. How about storing the last toucher's key in a global variable and using that?

That did it!! Thanks
