RE: creating new sheet
where you have your sheets listed there is a little button next to it with a yellow star on it. click on that and it will create the new sheet for you.
RE: creating new sheet
Erika,
You can right click an existing sheet tab (usually at the bottom of Excel) to bring up a context menu. Choose Insert..., ensure the default selection is 'worksheet' and then press Okay. A new sheet will have been inserted, which you can then rename by right clicking on the sheet tab.
I will mark this question as resolved for you.
If you have any other questions, please ask a new question, or reply to this post and mark the question as 'unresolved'.
Hope this helps.
Regards, Rich
