Hi Kristin, I answered your cut an paste in the discussion but maybe this helps too. If you click on view more sizes on rh side of your box you then choose main, click onto it and copy, then go back to the discussion and paste . Hope this helps.
@jennywren - Thanks Jen. Tried your advice, but still getting the error. Grrr... I'm wondering if the slow internet connection that we have here in Oman might be the culprit?
