MC thanks yet again you pointed me in the direction to fix it.

In the older version of EP it created 2 columns, v_categories_name_1 and v_categories_name_2

1 had Inkjet in and 2 had Advent in, I deleted the 2 column and changed 1 from Inkjet to Inkjet^Advent, re imported the CSV and it worked a treat.

Many thanks once again buddy, it is much appreciated..
