Dialogue nesting problem

Im rather new to sl, however I managed to get this far. My Dialogue button to call another dialog menu doesn't work for some odd reason. Can't figure it out.
Consideration is appreciated

...
llListen( 4913, "", NULL_KEY, "";
...
touch_start(integer total_number)
{
llDialog(llDetectedKey( 0 ), "Options", ["Goodwill"], 4913);

}
listen(integer channel, string name, key id, string choice )
{
if(llListFindList( menu, [ choice ]) != -1 )
{
if ( choice == "Lights" )

{
llWhisper(0,"Goodwill ";
llDialog(llDetectedKey(0), "Goodwill", ["no thanks", "please do"], 4913);

}

The script gets to goodwill, the following llDialog function is ignored.

Thanks!

if ( choice == "Goodwill" )

this doesnt make much since

llDialog(llDetectedKey( 0 ), "Options", ["Goodwill"], 4913);

sends a dialog with the window text reading options and a button labled "Goodwill"

listen(integer channel, string name, key id, string choice )
if(llListFindList( menu, [ choice ]) != -1 )
{
if ( choice == "Lights" )

{
llWhisper(0,"Goodwill ");
llDialog(llDetectedKey(0), "Goodwill", ["no thanks", "please do"], 4913); 

this wouldnt comple anyways

listen(integer channel, string name, key id, string choice )
{
    if(llListFindList( menu, [ choice ]) != -1 )
    {
            if ( choice == "Lights" )
           {
                llWhisper(0,"Goodwill ");
                llDialog(id, "Goodwill", ["no thanks", "please do"], 4913); 
           }
    }
}

this would compile but your first checking to see if the input is on a list which isnt neccacary, then your not testing for exact phrase "Goodwill", your testing for the string "Lights", so whisper and dialog would never fire under these conditions

and the main question is in llDialog you dont use llDetectedKey anymore, llDetectedKey only works with physical interaction, when chat is received the uuid of that av is returned as key id, just as string choice would for your options

ok,thx.
using llmessagelinked and loading a dialogbox fom another prim works also.

Cheers,
