VBA variables and offset

Im having trouble takign my assigned variable and offseting it. What am I doing wrong?

Public Sub SampleBox_Change() 
    Dim str As Integer 
    If (SampleBo开发者_Python百科x.ListIndex > -1) Then 
        str = SampleBox.List(SampleBox.ListIndex) 
    End If 
End Sub 

Public Sub Samplesdel(str As Integer) 
    Range(Range("BA1").EntireColumn, Range("BA1").Offset(0, -str).EntireColumn).Select 
End Sub 

Public Sub CommandButton1_Click()
    Application.Run "Samplesdel" 
End Sub

So the variable (str) is a whole number. I would like to use this number to select a certain number of columns (from BA1 to "left however many columns valued as str"). so if the user selects 8 i would like to select BA1 and left 8 columns.

The combobox is in a userform where the code for the assigned variable is set.

I would like to use the assigned variable in a macro (where i used the select function).

so the variable str gets assigned from a userform combobox. I would then like to pass this variable to a macro where i use it in the offset function.

I just used your snippets of code here, I'll assume you know what you're trying to accomplish with this. As mentioned in another answer, I think it's an issue of scope; it doesn't seem like there's a good reason you can't combine your statements as follows:

Public Sub SampleBox_Change() 
        Dim str As Integer 
        If (SampleBox.ListIndex > -1) Then 
            Range(Range("BA1").EntireColumn, Range("BA1").Offset(0, SampleBox.ListIndex).EntireColumn).Select
        End If 
    End Sub 

To add some unsolicited feedback, naming a variable that is an integer "str" will be very confusing to anyone else that has to read your code, the name "str" implies "string", a different data type.

James, you are setting the value of str here correct?

Public Sub SampleBox_Change() 
    Dim str As Integer 
    If (SampleBox.ListIndex > -1) Then 
        str = SampleBox.List(SampleBox.ListIndex) 
    End If 
End Sub 

The scope for str will only be this function and it will not be able to be accessed by any other function.

What value are you passing to Samplesdel as the parameter?

Application.Run "Samplesdel"
