I have a workbook with 4 sheets that is pretty well set...I have to add one
or two columns to one sheet for some important additional functions...?..do
I have to also rewrite or modify a macro I have to format the sheet...or
will the macro "update" as a result of the column additions.

I have four sheets in the workbook...do I need to update each and every
sheet with the new columns...even though they are only going to be used in
sheet 1 for the macro to work properly on all sheets ?

Thanks, Tim R
