Beginner Trouble (Fundamental Data)

I seem to be having a little trouble getting the ROE data to work. It keeps logging a context error, definitely a simple fix but I'm stuck on this. Any help would be greatly appreciated. Thank you.

import numpy 

def initialize(context):  
    context.limit = 3    

def before_trading_start(context):  
    context.fundamentals = get_fundamentals(  
        query(  
           fundamentals.valuation_ratios.peg_ratio,  
           fundamentals.operation_ratios.roe,  
        )  
        .filter(fundamentals.valuation_ratios.peg_ratio < 1)  
        .order_by(  
           fundamentals.valuation.market_cap.desc()  
           fundamentals.operation_ratios.roe.desc()  
        )  
        .limit(context.limit)  
    )  

    context.hello = context.fundamentals  
    update_universe(context.hello.columns.values)  
    print "___________________________________\n"

def handle_data(context, data):

        for stock in range(context.limit):  
            print context.hello.columns[stock]

You were missing a comma between your two order_by arguments, lines 14/15. Here you go:
