Hi,

This is clearly a much simplified example and probably doesn't represent the size or layout of your actual data. We often find that when we give an answer to what is a trivial non representative example when the solution is used with the real world data it doesn't work because of factors like string length and other stuff which is important but hasn't been mentioned.

In this case the system needs to know what the previous scores were. It's not clear whether the table you show will simply be replaced by a week 11 table, in which case the week 10 data will need to be recorded -probably in an additional column, or whether you record week 11 scores underneath the week 10 scores. Normally these sorts of record systems hold previous rounds/weeks/whatever scores in columns alongside the players names.

Therefore upload your real workbook (or at least a cut down copy), and manually add the results you expect to see.
