This example macro shows how to use the macro above:
Sub TestCompareWorksheets()
' compare two different worksheets in the active workbook
CompareWorksheets Worksheets("Sheet1"), Worksheets("Sheet2")
' compare two different worksheets in two different workbooks
CompareWorksheets ActiveWorkbook.Worksheets("Sheet1"), _
Workbooks("WorkBookName.xls").Worksheets("Sheet2")
End Sub

You just have to copy the two example procedures above and paste them into a normal module sheet in your workbook (you can't use the sheet modules).
Open a workbook that contains two sheets you want to compare.
Edit the sheet names used in the macro "TestCompareWorksheets" (or, if you are lazy, rename the sheets in the workbook).
In Excel you press Alt+F8 to open the macro dialog box and run this macro: "TestCompareWorksheets".
A more detailed description of this procedure is available here:
