<< I understand that I may need a vertical line. However >>
My apologies. I completely missed the fact (clearly stated in the first line of your question) that you were doing this with multiple columns, rather than simply columns of data fields. I promise answer any more questions before coffee! The only suggestion I can make for your situation is to read the LEFT property of one of the field in the ON FORMAT event of the detail band. Hopefully, R:Base will report back the LEFT property with respect to the entire page, rather than the left margin of the column (which would not be helpful). You could then decide, based on the LEFT property, whether you're in the first column or not and hide or make visible the vertical line component accordingly. -- Larry
