Errors
This page should contain a list of all the errors from the ti-nspire. Would like it set up similarly to errors
This table lists all the possible error messages that can occur. The error number to the left is not displayed, but is stored to the errornum system variable, which can be used in a Try..EndTry block. Some error messages are very explicit (like #680), but others are less so. Where the error message itself gave too little information, this table explains the error more thoroughly.
A large part of the information here was taken from the Nspire CX Reference Guide at education.ti.com
Errors need to be added to the table below. Please alternate between using error1 and error2

| 270 | Duplicate Variable | A variable with that name already exists |
| 280 | Invalid Else | An Else or ElseIf statement was outside the If-EndIf block |
| 290 | EndTry Missing Else | EndTry is missing the matching Else statement |

| 300 | List or Matrix Expected | Expected a 2 or 3 element list or a matrix as an argument |

| 320 | Equation or Inequality Expected | The first argument of solve or cSolve must be an equation or inequality solve(3x^2-4,x) is invalid because the first argument is not an equation |
| 345 | Inconsistent Units | The calculation cannot be performed with mismatched units Ensure all units are matching |
| 350 | Index Out Of Range | The index specified is not valid |
| 360 | Indirection String | Indirection string is not a valid variable name |

| 430 | Invalid For Mode | The calculation, command, or answer is not valid for the current mode settings |
| 435 | Invalid Guess | The guess is not valid |
| 440 | Invalid Implicit Multiplication | This is to prevent errors between implied multiplication and function calls x(x+1) is invalid, whereas x*(x+1) is the correct syntax; (x+1)x may also work, but not much is known about this |
| 450 | Invalid Command Use | Invalid in a function or Current Expression Only certain commands are valid in a user-defined function. The command which this error references cannot be used in a user-defined function |
| 490 | Invalid in Try..EndTry Block | The command is not valid in a Try Block |
| 510 | Invalid List or Matrix | The List or Matrix is undefined or not valid |
| 550 | Invalid Command Use | Invalid outside function or program A number of commands are not valid outside a function or program. For Example, Local cannot be used unless it is in a function or program |
| 560 | Invalid outside Loops | The command must be within a Loop..EndLoop, For..EndFor, or While..EndWhile block Certain commands, such as Exit are only valid inside loop blocks. |
| 565 | Invalid Command Use | Invalid outside program The command can only be used in a program, and is invalid in a function or on the home screen |
| 570 | Invalid Path Name | The specified folder or path is invalid Notably, \var is considered invalid |
| 575 | Invalid Polar Complex | The Polar Complex is invalid or could not be resolved |
| 580 | Invalid Program Reference | Programs cannot be referenced within functions or expressions Example: 1+p(x) throws this error when p( is a program |
