Hey folks,

I've been struggling with this for some time, and after fairly extensive searching I still haven't come across a good answer.

What I am attempting to do is have my spreadsheet automatically detect and highlight personnel working seven days in a row. There are 63 total columns, the first one being for the person's name. The next 31 columns are a full month's dates in which their day shifts are recorded, while the final 31 are the full month's dates for night shifts worked. Days worked are listed as a "1" in the cell beneath the respective shift's date, while days off go down as "3". Currently I am using conditional formatting with the following formula, which highlights cells in red:

=ISNUMBER(FIND("1111111",(H7&I7&J7&K7&L7&M7&N7&O7&P7&Q7&R7&S7&T7&U7&V7&W7&X7&Y7&Z7&AA7&AB7&AC7&AD7&AE7&AF7&AG7&AH7&AI7&AJ7&AK7&AL7)))

I created the conditional formatting formula to apply to the row for the first person listed, and then copied and pasted the formatting only for the rest of the personnel rows. The issue I'm having is that while it will highlight the seventh work days, it will often highlights all cells prior to the grouping which has seven straight days of work. It also tends to highlight single or multiple cells in red which do not fit the pattern, and whose rows may not even have seven straight days of work. Hopefully that's descriptive enough, any help would be greatly appreciated!
