First argument of nSolve must be a univariate equation
The first argument must be an equation, and the equation cannot
contain a non-valued variable other than the variable of interest. For
example, nSolve(3x^2
-
4=0, x) is a valid equation; however,
nSolve(3x^2
-
4, x) is not an equation, and nSolve(3x^2
-
y=0,x) is not
a univariate equation because y has no value in this example.
320
First argument of solve or cSolve must be an equation or inequality
For example, solve(3x^2
-
4, x) is invalid because the first argument is
not an equation.
330
Folder
An attempt was made in the VAR-LINK menu to store a variable in a
folder that does not exist.

Inconsistent units

Index out of range
360
Indirection string is not a valid variable name

Invalid assignment
400
Invalid assignment value

Invalid axes
410
Invalid command
420
Invalid folder name
430
Invalid for the current mode settings
440
Invalid implied multiply
For example, x(x+1) is invalid; whereas, x
∗
(x+1) is the correct
syntax. This is to avoid confusion between implied multiplication and
function calls.
450
Invalid in a function or current expression
Only certain commands are valid in a user-defined function. Entries
that are made in the Window Editor, Table Editor, Data/Matrix Editor,
and Solver as well as system prompts such as Lower Bound cannot
contain any commands or a colon (:). See also “Creating and
Evaluating User-Defined Functions” in the
Calculator Home Screen
module.

Label names must follow the same rules used for naming variables.

For example, a list inside a list such as {2,{3,4}} is not valid.
