I put several check boxes on a chart and assigned different macro to each of
them.

All each macro is doing is hide-unhide a specific column. Say I have ckeck
boxes "Weight", "Length" and "Width". Assigned macro A, B and C accordingly.
When I click "Weight" checkbox it calls macro "A" which toggles "hidden"
status for column "J". So all macro have same functionality, only for
different columns.

I would like to build a _single_ macro, capable to know which control box
was clicked.

So, all check boxes will be assigned the same macro and that macro should be
able to receive check box name as a parameter and then use a CASE statement
(or several IFs) to process appropriate columns.

Is it possible and, if yes, how?

Thank you
