Amazon Sellers help

I know a few of you on here have sold with Amazon sellers / FBA before.

Can anyone help me out with some product listings + figuring out how to do the Product Variations? **** is SO confusing and amazon sellers support is bargain basement quality.

I'm trying to add clothing. 5 different styles (products) with different colour options + size options

I think they have been approved for a GTIN Exemption too.

thanks
