Using Named Range to Display/Not Display Data how is it working on my sheet?

Hi everyone

Really up against it and not something I have done before, I have a RACI sheet which has some check box controls on it which when ticked/deticked, change a named range from True/False and then this then removes data or adds it back onto a sheet much the same as an auto filter check box would do.

I need to extend the range of these checkbox actions as I need to add columns to the sheet but have no idea how I do this.

Can someone please tell me.

The controls start in column x1
Thanks
