Handling Errors Resulting from Attached Formulas
On the home screen, you can attach to a list a formula that references another list with
dimension 0 (Chapter 11). However, you cannot display the formula-generated list in the
stat list editor or on the home screen until you enter at least one element to the list that
the formula references.
All elements of a list referenced by an attached formula must be valid for the attached
formula. For example, if
Real number mode is set and the attached formula is log(L1),
then each element of
L1 must be greater than 0, since the logarithm of a negative
number returns a complex result.
Notes:
• If an error menu is returned when you attempt to display a formula-generated list in
the stat list editor, you can select
2:Goto, write down the formula that is attached to
the list, and then press ‘Í to detach (clear) the formula. You then can use
the stat list editor to find the source of the error. After making the appropriate
changes, you can reattach the formula to a list.
• If you do not want to clear the formula, you can select
1:Quit, display the referenced
list on the home screen, and find and edit the source of the error. To edit an element
of a list on the home screen, store the new value to
listname(element#) (Chapter 11).
