You need to read the error message and add the missing character or value it requests.
This error happens in several cases:

1. You wrote an identifier (variable or function name) in the wrong place.
2. You wrote a keyword like [code]var[/code], [code]func[/code], [code]for[/code], or [code]signal[/code], and you did not follow it by a name.
3. You wrote a function definition but forgot the parentheses before the colon.
If the error tells you it expected something, you likely forgot to write a name after a keyword like [code]var[/code], [code]func[/code], [code]for[/code], or [code]signal[/code], making your code invalid. Or you forgot parentheses in a function definition. You can address the error by adding the missing name or parentheses.

If the error says you have something unexpected, you are likely missing a keyword like [code]var[/code], [code]func[/code], [code]for[/code], etc.

Another possibility is that you need to write a colon at the end of a function definition, [code]for[/code] loop, or a line starting with [code]if[/code], [code]elif[/code], or [code]else[/code].
This error tells you that you are missing a type somewhere. A type can be [code]int[/code], [code]float[/code], [code]String[/code], [code]Array[/code], [code]Vector2[/code], and many identifiers representing a data structure.

Most of the time, this error occurs when you wrote a colon after a variable name but did not follow it with a type name.

It also occurs when you write an arrow ([code]->[/code]) after the parentheses of a function definition but do not follow it with a type name.
To solve this, you need to write the name of the type after the colon, arrow (in the case of function return types), inside parentheses (for export types), or after the [code]as[/code] keyword.
The variable, function name, or class name you are trying to use does not exist.

You most often get this error when you make typos. Maybe you swapped two letters, forgot a letter... sometimes, it's hard to spot.

The other cause for this error is that you didn't define the variable, function, or class you're trying to access.
To solve this error, triple-check that there is no typo in the line.

If you can, try to go to the variable or function definition, double-click the name, copy it, and paste it where you see the error.

If you don't see any typo, then you need to ensure that you defined the variable, function, or class you are referring to.
You can only use keywords like [code]break[/code] or [code]continue[/code] in a loop. Outside a loop, they are invalid.

The [code]continue[/code] keyword means "jump to the next iteration of the loop." And the [code]break[/code] keyword means "end the loop right now and jump to the first line of code after the loop block.
If you wrote one of these keywords outside a loop, you need to remove it.

If you are trying to use it inside a loop, your indentation is most likely at fault. You may need to insert one or more leading tab characters to the keyword.
When the computer talks about a constant expression, it expects a fixed value, a fixed calculation, or the name of an existing constant.

In other words, it wants something that can never change. This is why the computer will reject function calls and variables where it needs a constant expression.
You need to replace function calls or variables with a constant value like a whole number, decimal number, string, vector, a predefined array, etc.

You can also use arithmetic operators like multiplications (*), additions (+), and so on.
