Please refer to the attached sample...
You should probably avoid using check boxes for this one as it would allow you to select more than one column in each of the 20 rows... option buttons are better in my opinion.
I didn't understand the last part, though: Figure Showing with "Out of Calculation like "88 out of 100". Could you explain it better?
Appreciate your prompt reply...but the figures in Grand total changes whenever i tick other boxes....grand total is like marks...60 out of 100 but the figure 100 changes as the value in J34 changes
