Perhaps you mean workBOOK instead of worksheet??
what did you try to name it?

I am getting the message that i've either entered a wrong symbol, used too
many letters..., but i did not and now it won't take any name. On the
other
worksheet the extension xls appeared on the tab. And I can't close
anything
or save my Excel file. HELP!!!
