Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a new report called Segregation to look something like this:

List of films with row numbers

For each film we show the two fields shown and the row number (see hint below).

 

To show the row number, use the expression =RowNumber(Nothing).  This gives the row number across the scope of the entire table.

Now create a report variable called repRowsColoured, and set its value to be 5.

Change the back colour of each row to be pale blue if the row number is less than the value of this report variable, and run your report to check that the first 5 rows only are coloured:

Coloured rows at top

Only the first 4 rows should be coloured.

Try changing the value of your report variable - does your report still work correctly? If you're feeling ambitious, try setting the value of the report variable to:

=ceiling(count("DataSet1")/10)

This should automatically colour the first 10% of the rows of your report.

When you've finished trying out different values, close your report down.
