I'm trying to pull the daily value of VIX from quandl and then use it to test a trading plan. I've been able to get a dataframe with the daily VIX, but I can't figure out how to pull the actual number from this. Here is my code:

"""
This is a template algorithm on Quantopian for you to adapt and fill in.  
"""
from quantopian.algorithm import attach_pipeline, pipeline_output  
from quantopian.pipeline import Pipeline  
from quantopian.pipeline.data.builtin import USEquityPricing  
from quantopian.pipeline.factors import AverageDollarVolume  
from quantopian.pipeline.data.quandl import yahoo_index_vix as cboe_vix  
def initialize(context):  
    """  
    Called once at the start of the algorithm.  
    """  
    # Rebalance every day, 1 hour after market open.  
    schedule_function(my_rebalance, date_rules.every_day())  
    pipe = Pipeline()  
    attach_pipeline(pipe, name='VIX_pipeline')  
    pipe.add(cboe_vix.close.latest, 'vix')  
def before_trading_start(context, data):  
    """  
    Called every day before market open.  
    """  
    context.VIX = pipeline_output('VIX_pipeline')  
    context.spy = sid(8554)

    print context.VIX  
    # These are the securities that we are interested in trading each day.  
    #context.security_list = context.output.index  
def my_rebalance(context,data):  
    """  
    Execute orders according to our schedule_function() timing.  
    if context.VIX < 14:  
        order_target_percent(context.spy, 0.1)  
    if context.VIX > 30:  
        order_target_percent(context.spy, -0.1)  
        """  
    pass  
def handle_data(context,data):  
    """  
    Called every minute.  
    """  
    pass

How can I get the value of VIX into a variable I can use in the if statements?

Thanks.
