you have first to make sure that your QlikView has some data which can be joined with the GeoQlik data (description done at http://demo.geoqlik.com/geoqlik/index.aspx ) . For countries it has then to match the Country Name, ISO2 or ISO3 code:
country_name country_code_iso2 country_code_iso3 Afghanistan AF AFG Angola AO AGO Bhutan BT BTN
The joint is case sensitive by the way. So, I suppose your data does not exactly match .
