whoops - missed that you were using the "array" directly:

Sub Check()
Dim wks As Worksheet, chbx As checkbox

For Each wks In Worksheets(Array("20", "21", "22", "78", "87"))
for each chbx in wks.CheckBoxes
chbx.Value = xlOn
next
Next

End Sub

or
Sub Check()
Dim wks As Worksheet, chbx As checkbox
Dim varr as Variant
varr = Array("20", "21", "22", "78","87")
For Each wks In Worksheets(varr)
for each chbx in wks.CheckBoxes
chbx.Value = xlOn
next
Next

End Sub

Hello. This is a follow up question to a previously posted question.
I have the following code saved to my personal workbook:


Sub Check()
Dim wks As Worksheet, chbx As Object

For Each chbx In Worksheets("20", "21", "22", "78",
"87").CheckBoxes
chbx.Value = True
Next

End Sub

Where 20, 21, etc are the actual sheet names. When I run this, I get
a Comile Error: Wrong number of argumants or invalid property
assignment. And the Debugger is pointing to the word "Worksheets"

Any ideas what I am doing wrong? Thanks!!
