Help please - can't save Excel spreadsheet - says it is Read Only!

[mishymoo]

Any ideas on how to save this to a USB Pen Drive?

I have copied and pasted spreadsheet into new work book but still won't let me save it!

TIA

Do file/save as
rename it

Thanks but have tried that and it still doesn't work! It's so annoying.

Is protection switched on? See under tools menu.

It doesn't look like protection is on. I have worked on this sheet loads of times and have copied and pasted it into a new workbook but it seems only when I try saving it on a pen drive it won't let me! aaargh!

Doah - blonde moment - I was saving it to the wrong pen drive! Sorry being really thick this morning! Thanks for all your sugestions.
