VBA - Selecting entire column

[satkin2]

Hi,
I've got a number of column groups that I want to perform various actions on. I've taken parameters to get these groups as follows...

Sub Get_Column_Groups()
    'Row titles
    Range("A1").Select
    Col_Group1_From = ActiveCell.Column
    Col_Group1_To = ActiveCell.Column
    Col_Group1_Width = Col_Group1_To - Col_Group1_From + 1
      
    'Months
    Col_Group2_From = ActiveCell.Offset(0, 1).Column
    Col_Group2_To = Selection.End(xlToRight).Offset(0, -9).Column
    Col_Group2_Width = Col_Group2_To - Col_Group2_From + 1
    
    'Blank
    Col_Group3_From = Selection.End(xlToRight).Offset(0, -8).Column
    Col_Group3_To = Selection.End(xlToRight).Offset(0, -8).Column
    Col_Group3_Width = Col_Group3_To - Col_Group3_From + 1
    
    'Monthly Movement
    Col_Group4_From = Selection.End(xlToRight).Offset(0, -7).Column
    Col_Group4_To = Selection.End(xlToRight).Offset(0, -7).Column
    Col_Group4_Width = Col_Group4_To - Col_Group4_From + 1
End Sub

What I now want to do is select the whole columns in say group2.

I can't work out how I select the whole column using these defined column numbers though. Would anyone be able to point me in teh right direction?

Many thanks

I forgot to mention, the groupings are defined globally...

Global Col_Group1_From, Col_Group1_To, Col_Group1_Width, _
       Col_Group2_From, Col_Group2_To, Col_Group2_Width, _
       Col_Group3_From, Col_Group3_To, Col_Group3_Width, _
       Col_Group4_From, Col_Group4_To, Col_Group4_Width, _
       Col_Group5_From, Col_Group5_To, Col_Group5_Width, _
       Col_Group6_From, Col_Group6_To, Col_Group6_Width
