Thanks Sheila. It appears you have paid twice for the Marzipan as you paid Sucadot £4 direct for it and you've also included it in the money sent to me.
So I think your Tally for the money you sent me should be:
Purchases
Hat from Madeleine £5
Cards from Her Majesty £16
Total £21
Sales
Cats Magnifying Glass £10
magnetic necklace Liverdodo £5
red necklaces Maelbrigda £2
Marzipan/bangle Meebo £5
Total £22
= £43
You have sent me £45 so you have overpaid by £2.
Is this right?
