Good day, I kind of summarized my problem in the title but I am going to attached the workbook and also explain what I'm struggling to achieve
we need to following to happen in this workbook

1.Unhide worksheets 1 to 21
2. Unprotect each worksheet -1 to 21 (password lss16)
3. Copy from worksheet "Master worksheet plus macro"
4. Copy to worksheets 1 to 21
5. Protect worksheets 1 to 21 again and then hide ws 1 to 21

Not sure what else to mention

Many thanks
