# Common Errors
|
|
|
|
## Attempt to call global '?' a nil value
|
|
|
|
**Description:** You tried to call a function that doesn't exist.
|
|
|
|
**Possible causes:**
|
|
* Your function might be defined in another Lua state. (e.g Calling a function on the client that only exists on the * server.)
|
|
* You're using a metafunction on the wrong kind of object. (e.g. Calling :SteamID() on a Vector)
|
|
* The function you're calling has an error in it which means it is not defined.
|
|
* You've misspelled the name of the function.
|
|
|
|
**Ways to fix:**
|
|
* Make sure the function exists
|
|
* Make sure your function is defined in the correct realm
|
|
* Check your function calls for spelling errors
|
|
|
|
|
|
## Attempt to perform arithmetic on global '?' (a nil value)
|
|
|
|
**Description:** You tried to perform arithmetic (+, -, *, /) on a global variable that is not defined.
|
|
|
|
**Possible causes:**
|
|
* You tried to use a local variable that was defined later in the code
|
|
* You've misspelled the name of the global variable
|
|
|
|
**Ways to fix:**
|
|
* Make sure you define local variables before calling them in the code
|
|
* Check for spelling errors
|
|
|
|
|
|
## Attempt to perform arithmetic on '?' (a type value)
|
|
|
|
**Description:** You tried to perform arithmetic (+, -, *, /) on a variable that cannot perform arithmetic. (e.g. 2 + "some string")
|
|
|
|
|
|
## Attempt to index global 'varname' (a nil value)
|
|
|
|
**Description:** You tried to index an undefined variable (e.g. `print( variable.index )` where `variable` is undefined)
|
|
|
|
**Possible causes:**
|
|
* The variable is defined in a different realm
|
|
* The variable is local and defined later in the code
|
|
* You've misspelled the name of the variable
|
|
|
|
**Ways to fix:**
|
|
* Make sure the variable is only accessed in the realm it was defined in
|
|
* If the variable is local, define it before accessing it
|
|
|
|
|
|
## Malformed number near 'number'
|
|
|
|
**Description:** There is a malformed number in the code (e.g. 1.2.3, 2f)
|
|
|
|
**Possible causes:**
|
|
* An IP address was written as a number instead of a string
|
|
* Incorrect writing of multiplication of a number and a variable
|
|
* Trying to concatenate a number to a string without a space between the number and the operator.
|
|
|
|
**Ways to fix:**
|
|
* Store IP addresses as a string
|
|
* Multiply variables with numbers by using the ***** operator
|
|
* Put a space between the concat (**..**) operator and the number.
|
|
|
|
|
|
## Unexpected symbol near 'symbol'
|
|
|
|
**Description:** You typed a symbol in the code that Lua didn't know how to interpret.
|
|
|
|
**Possible causes:**
|
|
* Incorrect syntax (e.g. Forgot to write "then" after an if statement)
|
|
* Not closing brackets and parentheses at the correct locations
|
|
|
|
**Ways to fix:**
|
|
* Make sure there are no mistypes in the code
|
|
* Close brackets and parentheses correctly (See: Code Indentation)
|
|
|
|
|
|
## 'symbol1' expected near 'symbol2'
|
|
**Description:** Lua expected symbol1 instead of symbol2.
|
|
When 'symbol2' is <eof>, Lua expected a symbol before the end of the file
|
|
|
|
**Possible causes:**
|
|
* Not closing all brackets, parentheses or functions before the end of the file
|
|
* Having too many `end` statements
|
|
* Wrong operator calling (e.g. "==" instead of "=")
|
|
* Missing comma after table item.
|
|
|
|
**Ways to fix:**
|
|
* Close brackets and parentheses correctly (See: Code Indentation)
|
|
* Use the correct operators
|
|
* Add a comma after a table item
|
|
|
|
## Couldn't include file 'file' - File not found (<nowhere>)
|
|
**Description:** The file system tried to include a file that either doesn't exist or was added while the server was live.
|
|
This error can also be a `AddCSLuaFile` error.
|
|
|
|
**Possible causes:**
|
|
* Attempting to include / AddCSLuaFile a file that doesn't exist or is empty
|
|
* Creating a file while the server is still live
|
|
|
|
**Ways to fix:**
|
|
* Add the non-existent file, make sure the file isn't empty
|
|
* Restart the server |
