unhide rows on sheet2 based on the values of checkboxes on sheet1

I have a workbook with three worksheets. On the first worksheet the user is asked to click "relevant" checkboxes that relate to their project. Based on these checkboxes one thing happens but on two worksheets:

On the first worksheet (same as checkboxes) 1. related rows appear when checked and disappear when not checked. This I have managed to figure out using the following code for each checkbox (I have 8 checkboxes):

Private Sub CheckBox1_Click()
    [22:25].EntireRow.Hidden = Not CheckBox1
End Sub

On the second worksheet 2. Same as above but on a different sheet, I would like the same result of related rows appearing when checked and disappear when not checked. I am not sure how to refer to another worksheet, and / or if there is a way to insert another line to the above.

Any help is appreciated.
