Finding Location Code

Good day

I hope you can help me please.

I have the following level of the location hierarchy : Country

I have created CountryCode and CountryDesc attributes based off this and have loaded the attributes from the correct position in the loc.csv.dat file into the attribute

Within my workbook - i have 5 countries. I want it to display the countrycode from the countrycode attribute so that i can use it in a calc to determine which countries i want to include in a calc.

So say I only want to include Namibi (code 1) and Nigeria (code 2) and exclude the rest in a foreign sales calculation using that country code (as that is set and will never change in the structure)
