llListen or listen(blahs) broken?

For some reason when i am typing it keeps making the script function on and off, like making the the light flicker on and off and then stays off. It's just a simple script and should function properly in theory but it's not...
//this is the main one in main prim

default
{
    state_entry()
    {
        llListen(0, "", llGetOwner(), "");
        llSetPrimitiveParams([PRIM_POINT_LIGHT, TRUE, <1, 1, 1>, 1.0, 2.0, 2.0]);
    }

    listen(integer chan, string name, key id, string message)
    {
        if (message = "lighton")
        {
            llSetPrimitiveParams([PRIM_POINT_LIGHT, TRUE, <1, 1, 1>, 1.0, 2.0, 2.0]);
            llMessageLinked(LINK_ALL_CHILDREN, -999, "lighton", NULL_KEY);
        }
        if (message = "lightoff")
        {
            llSetPrimitiveParams([PRIM_POINT_LIGHT, FALSE, <1, 1, 1>, 1.0, 2.0, 2.0]);
            llMessageLinked(LINK_ALL_CHILDREN, -999, "lightoff", NULL_KEY);
        }
    }
}

//this is the lil one in the child prim

default
{
    state_entry()
    {
        llSetPrimitiveParams([PRIM_POINT_LIGHT, TRUE, <1, 1, 1>, 1.0, 2.0, 2.0]);
    }

    link_message(integer sender_num, integer num, string str, key id)
    {
        if (num = -999)
        {
            if (str = "lighton")
            {
                llSetPrimitiveParams([PRIM_POINT_LIGHT, TRUE, <1, 1, 1>, 1.0, 2.0, 2.0]);
            }
            if (str = "lightoff")
            {
                llSetPrimitiveParams([PRIM_POINT_LIGHT, FALSE, <1, 1, 1>, 1.0, 2.0, 2.0]);
            }
        }
    }
}

Please try it and see if it is messing up for you. I looked in jira and these forums abit but nothing indicating a prob

nvm i messed up the whole == part. Thanks!
