greetings, am using Application.WorksheetFunction.Match, using 0 - for exact
match, comparing two ranges (one in sheet1, other sheet2). i want to
highlight the columns of range in sheet2 which are not included in range in
sheet1. running into problem, i think, because when there is column which is
not in sheet1 range the function returns value equivalent to "N/A". have
tried using:

Application.WorksheetFucntion.IsNA(WorksheetFuncti on.Match()) but can't get
this to work. any and all suggestions appreciated, thanks!
