Modify code to perform on multiple worksheets

I have the following code that runs every 10 seconds on the worksheet "Sheet1" in my workbook. How can I change the code to perform the exact same procedure on "Sheet2" in addition to "Sheet1"?

That code does not work. Sheet1 and Sheet2 need to be specified because there are other worksheets in the workbook

I don't understand what you are saying.

you changed the code to run on every worksheet. The code should only be run on Sheet1 and Sheet2
