Script to dynamically change the currency symbol.

I'm trying to write a script that would dynamically change the currency symbol based on the value of a Document Property.  Please note that I'm trying to do an exchange rate conversion, that's already been done in the DB; one column in USD amounts (USD_AMT), another in local currency amounts (LOCAL_AMT) and a column to identify the currency type of LOCAL_AMT called LOCAL_CURR.

I've researched this online and have managed to piece together the following:

curr = Document.Properties["DropDownCurrency"]

from System import Globalization
from Spotfire.Dxp.Application.Visuals import CrossTablePlot
from Spotfire.Dxp.Application.Visuals import CategoryKey
from Spotfire.Dxp.Data import *
from Spotfire.Dxp.Data.Formatters import *

tbl = ReportToPlot.As[CrossTablePlot]()
gbp = Globalization.CultureInfo("en-GB")
usd = Globalization.CultureInfo("en-US")

if curr == "GBP":
	lsf = DataType.Real.CreateCultureSpecificFormatter(gbp)
	lsf.Category = NumberFormatCategory.Currency
	lsf.DecimalDigits = 0
elif curr == "USD":
	lsf = DataType.Real.CreateCultureSpecificFormatter(usd)
	lsf.Category = NumberFormatCategory.Currency
	lsf.DecimalDigits = 0;

from Spotfire.Dxp.Application.Visuals import CrossTablePlot

tbl.MeasureAxis = CategoryKey('Variance')
#Properties.Formatter = lsf

As you see it's not complete; I'm not proficient in IronPython.  I think I'm on the right track but I'm not sure.  I'd really appreciate some assistance completing this script.  Thank you in advance.
