Hello all. I have the following bit of code:

Sub Uncheck()
For Each chbx In Worksheets("test").CheckBoxes
chbx.Value = False
Next
End Sub

I have workbooks with one checkbox on 100 sheets. How can I modify
the above code to uncheck each checkbox on every sheet?

Also, How could I modify it to check the box only on certain
predetermined sheets?

Thanks so much!
