llsay based on sound played

Before I drive myself batty:

I have a sound script I am playing with that might play any number of sounds in its inventory, I am wondering if its even possible to put an if statement in the common sound script that reads something like the following or am I going about it wrong - OR is it not possible (partial script to save space, its a fairly common one):

state_entry()
{
    integer sounds = llGetInventoryNumber(INVENTORY_SOUND);

    if ( sounds <= 0 ) state default;

    string soundname = llGetInventoryName( INVENTORY_SOUND, llFloor(llFrand(sounds)) );
    if ( soundname == "Sneeze male" )
    {
        llPlaySound( soundname, LOUDNESS );
        llSay("Excuse Me");

Seems reasonable to me. The code you posted wiill only play the sound if it matches the name you are looking for, is this the problem you are having? If so, you can put the llPlaySound() outside the name check:

state_entry()
{
    integer sounds = llGetInventoryNumber(INVENTORY_SOUND);

    if ( sounds <= 0 ) state default;

    string soundname = llGetInventoryName( INVENTORY_SOUND, llFloor(llFrand(sounds)) );

    llPlaySound( soundname, LOUDNESS );

    if ( soundname == "Sneeze male" )
        llSay("Excuse Me");

Actually the problem I am having is a syntax error when it hits the next line

state silent;

So I thought either I had the wrong idea about how to do it, or it wasnt possible.
The general idea is the inventory will hold a set of sounds, to which I will have a llsay for each sound randomly picked by frand (there are only about 5 or 6 sounds I plan to use) when chosen such as playsound Sneeze/say Excuse me etc, so far I am just trying to get a compile

// Sound Prim Script - Intermittent
//
// Randomly picks a sound in inventory, plays it,
// waits a random interval, repeats.
//
// Set this between 0.0 and 1.0
float LOUDNESS = 0.5;
//
// Interval in seconds to be silent.
// If you set these to be less than 10 seconds,
// they default to 10 seconds.
integer SHORTEST = 30;
integer LONGEST = 60;
//
////////////////////////////////////////////////
default
{

state_entry()
{
    if (SHORTEST < 10 )     SHORTEST = 10;
    if (LONGEST < 10 )      LONGEST = 10;
    if (SHORTEST > LONGEST) SHORTEST = LONGEST;

    llSleep( 1.0 );    
    state noisy;
}

on_rez(integer start_param)
{
    llSleep( 1.0 );
    state noisy;
}

}
////////////////////////////////////////////////
state noisy
{

state_entry()
{
integer sounds = llGetInventoryNumber(INVENTORY_SOUND);

if ( sounds <= 0 ) state default;

string soundname = llGetInventoryName( INVENTORY_SOUND, llFloor(llFrand(sounds)) );

llPlaySound( soundname, LOUDNESS );

if ( soundname == "Sneeze male" )
llSay("Excuse Me");
}
}
    
    state silent;
}

on_rez(integer start_param)
{
    state default;
}

}
////////////////////////////////////////////////
state silent
{

state_entry()
{    
    llSleep( (float)(llFloor(llFrand(LONGEST - SHORTEST)) + SHORTEST) );
    state noisy;
}

on_rez(integer start_param)
{
    state default;
}

}

Looks like stray bit of code got repeated. Might remove the lines:
that immediately precede...

Looks to me like you have two extra brackets above "state silent;"

Oh, yeah. That would make the braces match with the additional merit of actually making sense.
