CRELoaded Import Help

We are in the process of setting up our online shop, we have had many online stores in the past but until now have not come across the problem listed below. 1. Basically we have been given loads of csv files from our suppliers, these csv files contain all their products which are adult lingerie, being clothes each product can have many attributes such as size and colours. As you will see from the sample file there will be one main product for example: Sheer Leather Pantyhose which will have a master model of say: L001 and then each sub-product will be L001A L001B L001C Each one standing for a specific size or colour option. I am using creloaded 6.3 which I know includes sub-products but unsure of best way to import into the site, we are after a very simple and quick solution and maybe even some free advice if easy to do. I have included a sample of the file, We can supply the winner bidder with much more creloaded work as we want our store further customized, Regards John
