Public variables and Workbook_Open function

Question

I want to initialize some variable (like the ranges for graphs) in the Workbook_Open function in ThisWorksheet. This is done like:

Public ChartSizePosition As Range
Sub Workbook_Open()
    Set ChartSizePosition = Range("B8:I25")
    Worksheets("Übersicht").Range("A1").Value = "q3f"
End Sub

Afterwards I want to access the variable from some Sub in a module. But there is always given an error "Runtime error 424. Object necessary". The Workbook_Open code is definitely reached.

Anyone can give me a suggestion?

Best regards and thanks!

Answer 1

If you add a public variable to a class module (which ThisWorkbook is) you have to refer to the variable as a member of that class. So you have to refer to ThisWorkbook.ChartSizePosition rather than just ChartSizePosition .

Alternatively you can move the declaration to a normal module.
