Invalid name error when opening in excel


In order to get around not having the ability to directly copy an entire worksheet, I have added multiple copies of my worksheet to the designer file. I insert the data into as many as I need, and delete the unused sheets. I know this is not an elegant solution, but it will suffice.

However, when I do a mass deletion of sheets, I get an “invalid name error” whenever I open the modified workbook in Excel. Also, I am unable to open the workbook in the browser.
