I need to be able to change the column width on multiple columns (all
next to each other) on one sheet (i.e. codename: sheet10) based on
user data selected from a combobox on sheet1.

I have tried using this but it always fails, so I would really
appreciate any help on fixing it:

with sheet10 'codename for sheet
.unprotect
.columns(4,zColCount).columnwidth=dblColWidth ' col D thru # of
columns entered
.protect
end with

Thanks again....AJ
