Thanks Bev - I'll give them a go....and I still have your zoo container - I haven't forgotten! I hope you are both well and Happy New year to you.
Rich - thanks for your very kind offer. I don't want to put you out so I'll try and get something sorted - if not it would be great if I could give you a shout. Thanks for that.
I will kep you posted about my liquid retention problem...
