Thanks very much for doing that.... oh dear I'd hoped this website would cope with all the options as well as my last one, I have a lot more products all with a similar range of sizes and colours to copy over, I might have to think again.
Unfortunately the buttons didn't work right from the first option I entered, but I can see how the page had a melt-down, I had thought it would just make a drop-down a list of options to pick a combination from for one item, rather than each possible variation as a separate entity, which I don't really need.
