Not sure about that but I do know if you type the code
=RIGHT(CELL("filename",A1),LEN(CELL("filename",A1))-FIND("]",CELL("filename",A1))) into A1, it will say the Tab name as the text in A1. Thats the best I can do for you.
Thanks Hotpepper, but I must be doing something terribly wrong. I copy that code ( it's honestly the 40th or more that I've tried so far ) into a module for that sheet and click out of the module but the sheet still isn't renamed. Was I supposed to do something extra ??
Mine uses the Change event so that when you change the value in A1, it changes the name of the sheet. If you want to keep the existing value in A1, go into cell A1, hit the F2 key and then Enter. Then everytime you change this cell after that it will change the name of the sheet, assuming it is a valid sheet name.
