Hi...
I'm sorry if I can't replicate your condition.
Anyway, I macro recording your Conditional Formatting in cell B6 and then make the code below
The code will apply your conditional formatting (cell B6) and your concatenate formula (cell B10)
across to the right based on how many columns your "Incidents" table has.
So after you refresh your table, your table will expand to the right and has more column header.
Rather you make another conditional formatting and the concat formula manually,
you can assign the macro above to a button then click it.
Next thing is maybe you can try to have another code in Sheet1 module :
Hopefully with the addition code like above, when you refresh your "Incidents" table,
it will trigger the Worksheet_Change event and run the test sub without you have to click the button.
