New To Scripting

[ohheylookitsmax]

Hi everyone. I'm really new to scripting and creating custom stories. I keep trying to test out my map so far, but each time, I get an error notice as follows: FATAL ERROR: Could not load script file(my directories for my .hps)! main (10,1) : ERR : Unexpected token '{'
I assume it has something to do with the way I set up the script file. Here is my .hps file.

void OnStart()
{
AddUseItemCallback("", "FrontDoorKey", "Front_door", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
PlaySoundAtEntity("", "pick_key", "FrontDoorKey", 0, false);
}
{
SetSwingDoorLocked("Front_door", false, true);
PlaySoundAtEntity("", "unlock_door", "Front_door", 0, false);
RemoveItem("FrontDoorKey");
}

Any help would be greatly appreciated. I'm not sure where I can go online to learn about scripting, so if anyone knows where I might find that, it would also be a LARGE help. Thank you. Also, here while I'm doing this, I'm going to put my extra_english.lang script file down below as well to see if anyone can correct it, if needed.

To be clear, I read the important thread but I just don't get it. I tried following the instructions and it ended up creating more file problems.
Here's my file now:

void OnStart()
{
AddUseItemCallback("", "FrontDoorKey", "Front_door", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
PlaySoundAtEntity("", "pick_key", "FrontDoorKey", 0, false);
}

{
SetSwingDoorLocked("Front_door", false, true);
PlaySoundAtEntity("", "unlock_door", "Front_door", 0, false);
RemoveItem("FrontDoorKey");
}
the error report i get now is for lines 12 13 and 14 about needing expected identifiers. Basically they keep pointing out the parenthesis that I've marked in bold. I really don't know what to do. Please help.
