More errors!

Edit: I did not copy/paste the comments at the top of my file. Error 109 in my file is on line 87 bellow (and I have marked it inside the code, in case you copy and paste it to try for yourself).

I have succesfully created an Action Adventure Toy (based off the MoveToToy) and used the Knight Animation to move east and west. Now I wanted the toy to let you pick the hero (From Knight, Barbarian, Dwarf, and Wizard) with the default being the Knight. I got the list to populate (with some help from the Aquariam Toy) but I can't get any sprite to render now. The error message I recieve (per my log) is that there is a parse error on line 109 of main.cs.

Here's my code so far after some tinkering:

function ActionAdventureToy::create( %this )
{
    // Activate the package.
    activatePackage( ActionAdventureToyPackage );    

    exec("./scripts/HeroSelection.cs");

    // Initialize the toys settings.
    ActionAdventureToy.moveTime = 1000;
    ActionAdventureToy.setSelectedHero = "ToyAssets:TD_Knight_MoveWest";
    
    // Add the custom controls.
    addNumericOption("Move time", 100, 10000, 100, "setMoveTime", ActionAdventureToy.moveTime, true, "Sets the time it takes to move to the target position.");
    addSelectionOption(getHeroList(), "Hero Selection:", 4, "setSelectedHero", false, "Please select your hero.");
    
    // Reset the toy initially.
    ActionAdventureToy.reset();

To add to things, I'm occasionally getting a buffer overflow error when I try to reload/restart the toy. Only happened 3 times though.
