Edward, In the documentation for the formula type (from a formula type, press F1), you will find the following: NOTE: For periodicity checking, inside options, outside options, and the passes=o option to work correctly it is necessary to leave the result of the orbit calculation in the variable z. You would want to use z instead of z2, in the formula below. Jonathan
A further bit of code was required in the declaration of the formula .
