# 0107: Expected function return type

Compiler expected a valid identifier to follow a colon (`:`) in the [function](https://docs.sannybuilder.com/language/functions) signature but found something else.

E.g. consider this example:

```pascal
function bar():
```

The function definition ends with a colon implying a return type, but there is none defined. Or:

```pascal
function bar(): 5
```

Compiler found an integer literal, where a name of the type was expected.

#### Possible solutions:

* add one of the known [types](https://docs.sannybuilder.com/language/functions#signature) after the colon:

```pascal
function bar(): int
```

* if function returns nothing, delete `:` after arguments list

```pascal
function bar()
```
