>I somehow thought it was fixed - but it wasn't. I have a bunch of combos bound to two column arrays where some of the values are negative or zero (bound column is 2, column 1 contains descriptions, .bound=.t.). No matter what I do, the displayvalue remains blank for .value<=0... which isn't exactly helping.

As a work-around, what if you use transform() to convert to string the second column of the array? Then add a third column that has the numeric value and use it else where (or bound the third column and convert it to strings).
