I have a program with a whole bunch of similar grid questions (column oriented) that I will need to apply this to. There are 4 columns set with drop downs (hours, minutes, hours, minutes). The first two columns are one question about how much time and the last two columns are a different question about time. I don't want to force them to have to answer hours and minutes for every single row, but for each question I do want them to have to at least answer hours or minutes. So each row should have to have a response to either column 1 or column 2 AND to either column 3 or column 4.
There are a different number of rows on each of the grid questions throughout this program so I'm looking for some error scripting that could be used across these grid questions to accomplish this.
