Tutorial exercises on CGA - rule errors

[RichardMorris]

Hi, tutorial chapters 7 & 8 deal with creating CGA rules. On both exercises I have been unable to see the results as i'm getting errors from the rules I enter (cut & pasted from the guidebook). 

Screenshot attached.

Any solutions appreciated.

To see errors, open the Problems view (Window -> Problems).  Or, hover the mouse over the red X icon next to the line of code on which the error appears to see the error message.

In your screenshot, there are errors because the rules LFootprint and LShape are defined twice.  They can only be defined once.
