Its basically back to the beginning, that will make it easier to achieve, and that could take hours, although i do have a template of the basic structure.
Someone asked in the challenges once why i do it, I think they believe that i sit here and do a load of calculus each time, etc, but the reality is that its all set up so all i need to do is put in the figure that is declared, the rest is automatic. What i want to do now though, rather than having as many sheets as there are challenges, i want to design one input sheet that will automatically fill each challenge sheet, thus meaning i don't have to do duplicate data entry.
Have you followed me there? If so then perhaps i can delegate some of the work to yourself? would be a great help.
