Urrmmmm..... solved the puzzle.

Can you give me a few moments while I wipe the egg off my face ... (:(:

I've just realized ... I tried it again, the message came up "It appears you already have this product".

It then penetrated my thick skull .... I've already purchased that product !

I'm so embarrassed. Sorry for being rude (I'd had a bad day) and for the inconvenience.

Thanks for your forbearance :)
