hyperlink button to another worksheet

[jdwilson]

I have an existing button which has either a macro or hyperlink assigned to it which links to another worksheet within the workbook. I would like to change the worksheet it is linked to. I have tried right click - edit hyperlink and picked a different sheet, and also assign macro - record new macro. I have even removed hyperlink, then inserted new but no matter what it still goes back to the same sheet.

I am in this position after copying and pasting an existing button. I'm not sure how they designed it from scratch so I would really prefer to just change the link.
