VBA to group and hide/unhide columns in several Excel worksheets

I have a workbook with multiple sheets which are all formatted the same and I need to group the same columns on each sheet and I need to be able to hide them when I am finished entering data but then view them again the next time I need to edit the data. I have seen multiple VBA button examples on how to group and hide but not across multiple sheets. The sheets that need to be included are (TEMPLATE:UNIQUE) and the columns on each sheet that need to be grouped are (C:F) for one group and (I:P) for the second group.

Thank you very much .............................
