hi ood,
I belive your problem would be related to the apostrophy.. sometime punctuation causes problems when reading and writing string of text.
Try it without any puncitation and see wif it works.
Also try triggering the code with the debug.. and reviewing the log reat that section of the code.. sometimes that will give you - or me - some clues.
And for a happy easter present, I have fixed the code so the NEW cowmand now 'stacks' the worth as well as the quantity.. news
