This worked perfectly! Thank you!
You wouldn't be able to help in the next issue I've come across... Each category now splits into 3 further columns - t, f and N/A (as per the below screen shot). Is it possible, or do you know how I can have the result just displayed in one column and the result in the cell showing either "Yes" for t, "No" for f and "N/A" for N/A?
Once again, thank you for your help.
Try moving the Right to Work Calculation from the column shelf to the Text shelf on the marks card. Are you aware that there are some excellent free training videos available (click the On Demand tab).
