Simple Script Help

Hey all,

I've been working on a donation script. There is one part I'm stuck on - setting the goal. The piece of code below shows the part that is giving me trouble.

integer goal;
integer num;

default
{
    on_rez(integer start)
    {
        llResetScript();
    }
    state_entry()
    {
        ownerkey = llGetOwner();
        owner_name = llKey2Name(ownerkey);
        num = FALSE;
        llSleep(0.2);
        update();
        llSay(0, "Online!");
        llSleep(0.5);
        llListen(0, "",ownerkey,"");
    }
    listen(integer channel, string name, key id, string message)
    {
        if(num == FALSE)
        {
            if(llToLower(message)=="setgoal")
            {
                llSay(0, "Please say the number for the goal to be set to.");
                num = TRUE;
            }
        }
        else
        {
            (string)goal == (string)goal + message;
            num = FALSE;
            llSay(0, "Goal set to "+(string)goal+".");
        }
    }
}

Thanks in advance.

(string)goal == (string)goal + message;


Should be:

goal = goal + (integer)message;

Thanks a bunch

...be still my heart.
