Need Help with MicroTransactions!!!

[Sim220]

Hello!

I'm so f*king nervous because I'm trying to make the In-App-Purchases work. I have a Kismet node for it, but when I press the "buy" button it crashes the game.
Here's the code for the kismet node:

class SeqAct_MicroTrans extends SequenceAction;

var MicroTransactionBase MicroTrans;
var int IsHidden[2];
var bool isHiddenOne;
var bool isHiddenTwo;

event Activated()
{

	OnInit();

	CheckHidden();

	if (InputLinks[0].bHasImpulse) // Refresh
	{
		MicroTrans.QueryForAvailablePurchases();
		CheckHidden();
	}
	else if (InputLinks[1].bHasImpulse) // Product 1
	{
		MicroTrans.BeginPurchase(0);
	}
	 else if (InputLinks[2].bHasImpulse) // Product 2
	{
		MicroTrans.BeginPurchase(1);
	}

	MicroTrans.ClearDelegate(MTD_PurchaseQueryComplete, OnProductQueryComplete);
	MicroTrans.ClearDelegate(MTD_PurchaseComplete, OnProductPurchaseComplete);

	//PC.SaveVariables();
	
	
}

function OnInit()
{
	MicroTrans = class'PlatformInterfaceBase'.static.GetMicroTransactionInterface();
	MicroTrans.AddDelegate(MTD_PurchaseQueryComplete, OnProductQueryComplete);
	MicroTrans.AddDelegate(MTD_PurchaseComplete, OnProductPurchaseComplete);	
}

function CheckHidden()
{
	if(isHiddenOne == true)
	{
		ActivateOutputLink(0);
	}
	if(isHiddenTwo == true)
	{
		ActivateOutputLink(0);
	}
}

function OnProductQueryComplete(const out PlatformInterfaceDelegateResult Result)
{
	local int Index;
	local PurchaseInfo Info;
	for (Index = 0; Index < MicroTrans.AvailableProducts.length; Index++)
	{
		Info = MicroTrans.AvailableProducts[Index];

		if (Index < 2)
		{
			IsHidden[Index] = 0;
		}
		
		isHiddenOne = bool(IsHidden[0]);
		isHiddenTwo = bool(IsHidden[1]);

		`log("Purchase " $ Index $ ":");
		`log("  " $ Info.Identifier $ " - " $ Info.DisplayName $ " / " $ Info.DisplayPrice $ " - " $ Info.DisplayDescription);
	}
}

function OnProductPurchaseComplete(const out PlatformInterfaceDelegateResult Result)
{
	`log("Purchase complete:");
	`log("  Product = " $ Result.Data.StringValue);	
	`log("  bSuccess = " $ Result.bSuccessful);	
	`log("  Result = " $ Result.Data.IntValue);	
	

	if (Result.Data.IntValue == MTR_Failed)
	{
		`log("  Error: " $ MicroTrans.LastError);
		`log("  Solution: " $ MicroTrans.LastErrorSolution);
		ActivateOutputLink(2); // Failed
	}

	else
	{
		ActivateOutputLink(1); // Successful
	}
}

defaultproperties
{
	ObjName="In App Purchases"
	ObjCategory="Sim"

	InputLinks(0)=(LinkDesc="Refresh")
	InputLinks(1)=(LinkDesc="Product 1")
	InputLinks(2)=(LinkDesc="Product 2")

	OutputLinks(0)=(LinkDesc="Hide")
	OutputLinks(1)=(LinkDesc="Successful")
	OutputLinks(2)=(LinkDesc="Failure")
	
}

If anybody could help me, or anybody could write a step-by-step tutorial...I swear I'll pay him a lot of money! NO JOKE!
PLEASE HELP ME!!!!

I plan to set this up eventually but haven't yet so I'm interested....

Have you checked the log files on the crash? (probably a dumb question but..)Is it crashing on device or Mobile previewer? Maybe if you placed more `log()s & followed them in the output log file after the crash you'll be able to find out where your code is choking up...?

If the game close due to crash, with no error message, where on the device would I look for the error log file?
