Show/HIde Columns using VBA

I have 10 check boxes in a sheet and I want that for the range of columns from Column T to Column XR if Checkbox 1 is checked/unchecked then show/hide every 11th column
if checkbox 2 is checked show/hide every 12th column so if checkbox 1 is checked then Column T,Column AF,Column AR and so on should be shown and unchecked they should be hidden.
Thought?
Thanks!

John This works somewhat..
If checkbox1 is checked/unchecked it runs the code but I want it to run for the other checkboxes only when I do the instance for check uncheck..i don't want it to loop through and check for other boxes each time.

Not sure I understand.

See the sheet attached. I copied the code and applied to buttons.It hides it the first time then does not show them back again.

OK I think I got it working now !see Attached!
