i have 1 spreadsheet with 7 worksheets that requires a different header/footer in each ws. Any ideas?

In a spreadsheet with 7 worksheets how does a custom Header/Footer defined for each Worksheet?

Please try to find a “speaking” but concise subject. The details can wait for the body of your questiom.
What about “How to get different headers/footers for different sheets?” ?

(Spoken aside)
I have about two dozen city maps in my drawer. Most of them are older than 15 years, but all of them have printed “NEW!” on the cover. I would prefer the date of publication.
Software versions are distinguished by numbers in their specific way.

How to proceed now?
Could you work it out based on my answer or do you need detailed explanations?

Define as many page styles as you have sheets. Then define their properties and assign them to the sheets one by one as needed.
