Error Messages
When the TI-84PlusCE detects an error, it returns an error message as a menu title,
such as ERR:SYNTAX or ERR:DOMAIN. This table contains each error type, possible
causes, and suggestions for correction. The error types listed in this table are each
preceded by ERR: on your graphing calculator display. For example, you will see
ERR:ARCHIVED as a menu title when your graphing calculator detects an ARCHIVED
error type.
ERROR TYPE Possible Causes and Suggested Remedies
ARCHIVED You have attempted to use, edit, or delete an archived
variable. For example, the expression dim(L1) produces an
error if L1 is archived.
ARCHIVE
FULL
You have attempted to archive a variable and there is not
enough space in archive to receive it.
ARGUMENT A function or instruction does not have the correct number
of arguments.
The arguments are shown in italics. The arguments in
brackets are optional and you need not type them. You
must also be sure to separate multiple arguments with a
comma (,). For example, stdDev(list[,freqlist]) might be
entered as stdDev(L1) or stdDev(L1,L2) since the frequency
list or freqlist is optional.
BAD

between Left Bound and Right Bound.
For the solve( function or the equation solver, you specified
a guess that is not between lower and upper.
Your guess and several points around it are undefined.
Examine a graph of the function. If the equation has a
solution, change the bounds and/or the initial guess.
BOUND In a CALC operation or with Select(, you defined
Left Bound > Right Bound.
In fMin(, fMax(, solve(, or the equation solver, you entered
lower upper.
BREAK You pressed the É key to break execution of a program,
to halt a DRAW instruction, or to stop evaluation of an
expression.
DATA TYPE You entered a value or variable that is the wrong data type.
