We're using a matrix constant sum survey question to have respondents record a count each day for 1 month. Each column is a day of the week (Sun-Sat), but the first of the month is on a Wed so we don't want respondents to enter counts in the boxes for Sun-Tue of that first week. Validations prevent me from setting up a default answer of "X" in these 3 boxes. Is some kind of JS I can add that will allow me to gray just those 3 boxes out, and maybe prevent data entry?
Question
