"Cells" refers to the active sheet unless you tell Excel differently.
A hidden workbook is not active and has no active sheets.
Change your code so that "Cells" has a parent called out...
'---
Set mRng = _
Sheets("Picklist").Range(Sheets("Picklist").Cells( 2, "a"), _
Sheets("Picklist").Cells(2, "a").End(xlDown))

Hi All. I have the following bits of code:

Sub Main()
UserForm1.Show
End Sub

Private Sub UserForm_Initialize()
Set mRng = Sheets("Picklist").Range(Cells(2, "a"), Cells(2,
"a").End(xlDown))
For Each c In mRng
ComboBox1.AddItem c
Next c
End Sub

I would like my Sheet "Picklist" to be hidden. When it is hidden, my
code errors out on the line UserForm1.Show. When I unhide the sheet
"Picklist" and execute the code, it works perfectly.
Any ideas on how I can execute the code while the sheet "Picklist" is
hidden??
Thanks so much.
